The Diana 25 (this one says Winchester 425) was made for decades. It’s at the top of the youth line of air rifles from the ’50s through ’70s.
Before we begin, I owe you an explanation. Although the title of this report says the Diana model 25, the rifle we’ll look at is actually a Winchester model 425 — Winchester’s branding of the model from the 1970s. I used the Diana 25 model name because there are many times more Diana 25 air rifles than just the few thousand that carry the Winchester name. That way, all who read this will know the root airgun. If they ever need parts, they’ll know what to look for.
At most airgun shows, I buy and sell as much from/to the other dealers as I do to the public. I’ll often sit at my table with my eye on a certain gun for almost the entire show before making my move. I bought David Enoch’s Gamo 68 as we were packing up to leave the Malvern show. I’d wanted it all show long and hoped it would still be there when I sold something and had the money to buy it. When I did have the money, I found my self unable to open my wallet until David started packing it up to go.
The Fast Deer I bought at Roanoke this year is another example of the same thing. I had the money, but still I putzed around for no reason, arguing with myself over a $40 purchase!
And all the while we were at this show, I watched Mac’s Winchester 425 (Diana 25) sitting on the table next to me. He had it marked at $200, which is a very good price, because this is the model 25 that has the three-ball trigger. I had a Winchester model 427 (a Diana 27) for sale for $225, which is also a good price for that model, but people were overlooking my gun and focusing on Mac’s 25. His rifle is even cleaner than mine and frankly, at $25 less, it looked like a better deal.
Finally, after much agonizing and hand-wringing, I either bought Mac’s rifle or traded for it. I think we traded, which is always better, because then you never know for sure who got the better deal. It’s the old two $2,500 dogs for a $5,000 cat routine.
Every time I buy an airgun, I’m always justifying it by thinking that I’ll write a blog about it, which I almost always do. Sometimes, like the case of my Falke 90, I get so involved in the gun that I start investing even more time and money just because I get caught up in the story and want to see how it turns out. And, FYI, the Falke stock is on its way to the refinisher to get a new lease on life. The results of that will be coming in a separate report some time in the future.
Back to my report. So, I acquired this Diana 25, and now I want to share it with you. For years, Mac has told me that the 25 is just a 27 that’s a little shorter. I wanted to test that. Mac has had a whole collection of these guns, including several 27 and 25 airguns. He sold a 27 at the Roanoke show the year before, and I was sad to see it go — even though I have two of them myself and do not need another. Mac’s had more of these rifles than I, so I listen to what he has to say about them.
Diana 27 (top) was just slightly larger and more powerful than the 25.
The 25 stands out because there were several different versions of the same gun, built over the decades the model was being manufactured. There’s the 25 that has a more or less simplistic trigger with a direct sear. That one isn’t adjustable, as far as I know. It’s not a bad trigger, but it doesn’t compare to the model we’re examining here.
Then, there’s the model I’m testing for you that has two adjustment screws for the trigger — only one of which actually adjusts the pull. The other screw is nothing but a lock screw that holds the adjustment in place. People who are not familiar with the trigger adjustment process of the 25/27/35 will invariably mess up the adjustment and get a trigger-pull that’s single-stage, long, creepy and vague as to the let-off point. They’ll declare the trigger to be junk and get rid of the rifle when it could so easily be adjusted to a very fine pull if they only knew the secret.
The presence of two screws on a Diana 25 air rifle trigger signifies a ball-bearing sear trigger. The front screw (left) is just a locking screw.
Adjusting a two-screw, three ball-bearing sear Diana trigger
Here are simple instructions for adjusting the Diana 25/27/35 triggers that have two screws. The front screw is just a lock screw. Loosen it and then screw the rear screw in as far as it will go (that’s clockwise). Then, turn it back out two full turns and try cocking the rifle. Be careful not to let go of the barrel, because some guns may be adjusted to the razor’s edge this way. If yours is and you need a little more sear engagement, try turning the screw in or out just a quarter turn until the sear holds well. Next, tighten the front screw, and the job is done. You’ll have a long first stage followed by a definite stop and crisp stage-two break when the gun fires. You only have to experience one of these triggers adjusted correctly to know how nice they all are.
This trigger assembly from a Diana 35 is identical to the one found in the model 27 and the model 25 we’re examining. These parts are held together inside the gun by the spring tube. Assembly requires a lot of tacky grease to hold these parts together until they’re safely contained inside the spring tube.
There’s one more variation of the 25, and that’s a rifle with just a single trigger screw. It’s a later design that did away with the need for a locking screw by virtue of having the adjustment screw pass through more metal and be less resistant to movement. This one is much easier to adjust because there’s no chance of making a mistake with the locking screw since it isn’t there.
The rifle is small, being made primarily for youth. At just 37-3/4 inches overall, it’s sized like a carbine, though the proportions look more like those of a rifle. The pull is just 12-7/8 inches, which is short for an adult but about right for a teenager. Today, these rifles are more often used by older shooters than their builders intended. As Mac stated, they’re viewed as smaller model 27 air rifles — especially when they have the ball-bearing sear. The barrel is shorter than the one on the model 27, at 14-1/2 inches. The rifle still cocks easily because the mainspring isn’t that strong.
The stock is beech, which is stained very differently than the darker model 427 shown for comparison. There’s actually a pleasing grain that isn’t common to beech. The butt has a single rubber “button” at the top that confuses airgunners all the time. It’s there to keep the wooden butt from sliding across the floor when the rifle is stood in the corner. There’s a slab-sided profile to this 25 stock that isn’t seen on the 427. It just means they started with a thinner blank.
The metal parts are all well-polished and deeply blued. Today, the finish looks exceptional; but when this rifle was made, it was considered standard for the time.
The rifle weighs 5-1/2 lbs. on the nose. It feels like a gun you could carry and shoot all day.
This model came in both .177 and .22 caliber, though all the Winchesters I’ve seen were in .22 caliber. That’s a pretty large pellet for such a small powerplant, and you can expect velocities somewhere in the 400s with light- and medium-weight pellets. That sounds pretty anemic to those who are accustomed to supersonic velocities, but the fact is that these are pretty accurate at close range and a lot of fun to shoot.
Sights
The 25 and 27 air rifles have fully adjustable rear sights and hooded front posts that are fixed. There’s also a serrated ramp on the back of the spring tube that accepts a Diana peep sight, should you be fortunate enough to find one.
The rear sight adjusts in both directions. It’s crisp, clear and an example to all airgun makers today.
I’m testing this rifle because Mac has piqued my interest over the years. Normally, I would say the Diana 27 is the epitome of lightweight spring guns, but there might be something here that I haven’t yet seen. At any rate, it’ll be fun to find out!
I’ll take the two dogs…
Dogs want to please their owner — cats want the owner to please them..
Hmmm… Isn’t the T01 a three-ball lock-up? Though possibly different points for the balls… Maybe a comparison is justified (heck, I wouldn’t be surprised if you couldn’t get a two or three part blog out of just the variant Diana triggers!) I will have to concede that looking that the exposed trigger, this one looks lovely — pivot point above the blade, not an inch in front of the blade.
Based on the photo, the rear sight also has a choice of four notches (or maybe just two if the side “notches” are just indexing grooves). Either way — I adore the build of the sight…
You obviously have not met my dog.
I am the proud owner of not one, but two air rifles. One for plinking and possibly for my grandson to use/have when he is older if he desires to try 3P and one for long range plinking/vermin elimination should I feel the need to do such. I also have 46M for when I wish to plink with pistol and yes, if the grandson wants to borrow it, well…
I am an accuracy freak. When you guys see a sproinger produce sub 1 inch groups at 25 yards, you laud it’s merits and rush out and add one to your collection. Now should that said sproinger produce sub 1 inch groups at 50 yards, I would give it more serious consideration.
I shot my CFX for two years. In that time I was able to produce groups that would amaze most shooters, but not consistent enough for me. When an unnoticeable variance in the amount of pressure my thumb is applying can throw my group off two inches, this is not fun and it is totally unacceptable to me.
Now who knows what the future holds. Perhaps, when and if I retire, I may acquire a few quality sproingers such as this 25 to play with. I am not a collector, although it is tempting sometimes. I am a boy and like any boy, I want a lot of toys to play with. I just wish some other boy nearby had a bunch of these toys and would let me play with them.
Whew, that was long winded.
For those who shoot Exact RS…
The last two tins I got are a bit different than the previous. Both batches were in the red/white tins.
There is a bit of shape difference in the heads. The newest ones seem to be a little sharper around the outside edge of the heads. Seem to shoot O.K.
twotalon
They fit a bit tighter too.
B.B.
Any idea how much these rifles cost back when they were in production ?
twotalon
TT,
The in 1970 the Winchester model 427 was $39.95, and the 425 was $32.95.
B.B.
good reading!!
do you have any idea where I can find parts for my Winchester mod425????
O-rings ect.
Robert,
Try this guy:
B.B.
my mod425 is .22cal
Robert,
Welcome to the blog.
All Winchester airguns made by Diana like your 425 were in .22 caliber, only. Winchester never ordered any in .177, like other companies did.
B.B.
B.B.,
Nice to see a writeup on the Win. 425. I have the exact same model, also purchased from Mac at last year’s Roanoke show. These airguns are a joy to shoot and it is a shame that there is no equivalent sold in the USA these days. There are a number of low-power .177’s but finding one in .22 is almost impossible.
The trigger on my rifle is different from yours – it is plastic with a single adjusting screw and it is grooved instead of smooth. The rest of the trigger/sear assembly is the same.
Mine is a little picky on ammo – Premier Hollow Points, JSB 16gr, and JSB wadcutters do the best. The JSB RS and 14.9gr pellets do noticeably worse. It is also my only .22 that will not shoot FTS/FTT pellets well. Looking forward to the rest of the test.

I love little guns and the Diana 25D is one of my favorites. One time I bought a box of 6 non functioning Diana 25s. Most were Winchesters. I thought I would be able to do more with them but I found that out of 6 guns, I had 4 variants with different sized parts that would not interchange. I didn’t pay but about $60 for the box and I got one or two poor condition working guns out of the box so I was ok but somewhat disappointed. I guess the point here is not to assume you can swap parts on these guns. It may not work.
BB, I noticed in the picture that the loose spring in the trigger group seems to have a guide inside it. Is that a guide or a screw? Is that the spring that goes up top at the rear when you put the gun back together that holds tension on the two sleeves? I don’t remember seeing a guide like that. I can see that a guide at that place would be helpful because that spring always wants to bend as you put it back together. I usually put a twist tie around that spring to keep it straight as I start to compress the assembly back together and undo the twist tie when part of the spring is in the action.
I look forward to the rest of the report.
David Enoch
David,
You are correct – the spring fits between the two sleeves and the part in the spring is a short guide. It definitely helps during assembly.
Paul in Liberty County
David,
Yes, that is a spring guide and that’s wherte it goes.
B.B.
I think my Diana 24 (it’s similar to the now called 240) is my only springer that’s superior to the Bronco, and not by much!
I would have a hard time choosing between the two, I would probably keep the Bronco because it’s more unique…

So, what do folks here know about the HW55 with double set triggers that’s currently being discussed over on the Yellow?
http://www.network54.com/Forum/79537/thread/1352865201/
Very interesting. Are there many other examples of airguns with set triggers?
-Jan
Jan,
The HW55T DST that is being discussed on the yellow came from carel in the netherlands. One of my airgun friends here in Colorado thought about buying it and forwarded the pictures to me and asked my opinion since I own a few dst’s. That gun is in rough shape and I’m 99% sure that the stock isn’t original nor are the sights.
I own walthers and weihrauchs with double set triggers. Here’s one of mine that I recently posted about:
http://www.network54.com/Forum/405945/thread/1349056087/Walther+LG55+DST+Tyrolean
kevin
Kevin,
Spectacular! Wow!
How do you like the set triggers? How do they compare to newer match triggers, if that’s even a valid comparison?
Thanks,
Jan
Jan,
Thanks. It’s a fun gun with stunning accuracy.
I like single set and double set triggers. They’re single-stage with very light pull weights. That LG55 DST is set to a 2 ounce pull. You must have your crosshairs on target before you even touch that trigger. When B.B. talked about his recent acquistion of that wonderful Winchester High Wall with the single set trigger he was spot on with his description of these triggers.
Comparing a good sst or dst to “newer match triggers” would cover a lot of ground. Hopefully B.B. will address this in Part 3 of his “Trigger Happy” series.
kevin
Kevin,
Hmmm. Part three of Trigger Happy?
I had something else scheduled for tomorrow, but since I blew it today by posting a Friday blog on Thursday, you talked me into it.
Trigger Happy Part 3 it shall be.
I have something way cool to show all of you.
B.B.
Tom,
OOPs. Wasn’t trying to talk you into anything.
When YOU say, “something way cool to show all of you” my ears always perk up. Now the waiting.
kevin
All right! Kevin, you may not have been trying to talk B.B. into anything, but I’m glad you did!
-Jan
Jan,
Keep smiling! You’re in tomorrow’s blog, too. 😉

I too look forward to the rest of this report. I also purchased a 425 at Roanoke this year. My example has a box, instructions and a warranty card. It is in near perfect condition. It was marked at $225 but did not sell for most of the show. I walked between it and Mac’s several times Saturday morning. I think Mac would have taken $175 and I bought mine for $200. I thought the price was a bit steep but after traveling a long way to the show I wanted to bring something home. I also thought the extra $25 was worth it for the box and paper work so I ended up not buying Mac’s.
For what it’s worth mine is shooting 14.3 JSB Exacts around 420fps. It does not seem to be picky about pellets although I have not shot it a great deal. I really prefer .22 caliber despite the lower velocity.
I find mine to be such a looker that I am probably going to have to find a few more Winchester marked Dianas to add to my growing collection.
I think you got a great deal on that rifle. When the time comes to sell it, if it ever does, you should have no trouble making money.
B.B.
BB/Tom
Thanks, I have no regrets. After posting I put a few through the rifle and have a further note: for some reason my stock screws tend to come loose as the rifle is shot. Just the front ones and the left more quickly than the right. I realize that this is not uncommon with springers but I find it surprising in this one. The shot cycle is very smooth but still the screws come loose. Something to watch if your groups start wandering.
Sounds like it’s time for some Vibra-Tite on those stock screws.
kevin
Dianas have such a great reputation I’m always tempted to take the plunge, but two things stop me; I can’t shoot a springer worth a darn, and the weight. While most people claim they like a heavier rifle for stability reasons, I’ve found over the years I can shoot much better with a lighter gun. You mention the 27 as the epitome of light spring guns but I don’t see that listed at PA…is it no longer being made?
dangerdongle,
Never met anyone that didn’t like shooting my late model Diana 27. It makes an R7 look and feel huge. I think you would like it. Unfortunately production of the diana 27 ceased around 1987. You can find them if you search a bit.
Be aware the Diana 27 was also badged a Beeman 100, Hy-Score 807 and Winchester 427. Same gun.
Also be aware that the Diana Model 27L, 27A, 27E and 27S are similar to the Model 27 but are completely unrelated with virtually no common parts.
kevin
Does anyone else have the problem of their middle finger hurting after shooting a Diana 25 or 27 for awhile? When my trigger finger is on the trigger, the last joint of my middle finger is against the back of the trigger guard. After shooting for awhile, my middle finger gets pretty sore. I have tried using the middle finger on the trigger and that works but it is just weird.
David Enoch
David,
I have that problem when shooting a powerful Thompson Center Contender. The recoil drives the triggerguard back against my middle finger.
B.B.
Try shooting the first generation Contender with original “target” grip…
Took me one session with the .357mag Contender, back in ’79/’80 before I picked up a Pachmayr rubber grip for it. (Good thing I didn’t take the .30-30 model — only reason I went with the .357 was that the .30-30 action was too tight to open safely)
The original grip would be great with .22LR and maybe .22WMR — but anything bigger just resulted in trying to separate one’s thumb at the base joint.
I have one of the Diana 25’s by Winchester left to me by my Father (bought in the mid 70’s), and have always had a problem with shooting any .22 cal pellets. They tend to not want to seat in the barrel well enough and when you close the barrel, it mushes part of the rim of the pellet. I moved to shooting the 5mm european pellets and they seem to work much better and give greater accuracy in this rifle.
I as well have a Benjamin model 132 from the mid 70’s which shoots like a dream, and still has the original seals! I always kept one pump in the chamber when storing, and lubed it about every 3-5 years. Still works just like the day I took it out of the box. Great airgun.
And about the Tompson Center Contender, I have a couple of them, with around 10 barrels. My Father bought an original Contender (with the silver butt plate) with a 30-30 octagonal barrel at I believe $125 in the early 80’s. The first time we took it out for a shoot, he dislocated his thumb from the recoil of this terrible combination of a high shock callibur with a lightweight octagonal barrel. Ouch!
My favorite combination on the T/C Contender is with the .223 Rem (10 inch) bull barrel, Pachmeyer grip and forend with a Leupold M8 4x eer scope. I have worked up a hand load with 40 gr speer bullets to give 5 shot groups at 125 yards in under 3/4 inch. Soft recoil with the bull barrel, and 40 gr bullets, and no typical “Watermellon” plume of flames out the barrel, as can be seen shooting that dreaded 30-30. Ha!
Sorry about the abrupt turn away from the thread on airguns!
Mark,
Welcome to the blog. We don’t worry about staying on topic here, as you will see in tomorrow’s blog.
Come over to the current page to make your comments.
/blog//
As far as your Diana 25 goes, they don’t handle American-made pellets very well. Crosman pellets are too hard for the gun.
Use RWS Superpoints for great accuracy and seat the pellets deep in the breech top avoid bending the skirts. The breech is cut on an angle, which is what does that.
Use a ballpoint pen to seat each pellet.
B.B.
A question about setting the trigger. BB you mention holding onto the barrel. Do you make an adjustment and then test the trigger with the barrel broken, thus the need to hold the barrel? Or, do you adjust the trigger, break the barrel, load and shoot, where the warning is just in case the trigger is too light?
David,
What I meant is the sear may slip off if it is set too light. So NEVER let go of the barrel when you cock the gun. You shouldn’t let go of it anyway, because you never know when a breakbarrel is going to fire3 on its own.
Did that answer your question?
B.B.
Thanks B.B.,
Yes it did. Can you test the trigger with the barrel broken, as long as you are holding the barrel? For someone who doesn’t have much experience with shooting and the feel of triggers, would this make for quick, rough setting? Then fine tuning by firing?
David
In general that’s not a good idea. First of all, any time you intentionally fire the gun with the barrel open is an opportunity for disaster. Best not to make a habit out of it. Second: with many trigger mechanisms the pull weight is partially dependent on the spring load on the trigger assembly. When you release an open barrel this way you should pull the barrel all the way back, pull the trigger, then let the barrel forward. This means the sear is unloaded when pulling the trigger which can give a false feel.
And there’s the “anti-beartrap” issue – many guns simply won’t let you pull the trigger while the barrel is open.
David,
Yes, you can test the trigger while holding the barrel. You cannot feel how fine it is, but you can get a general idea of whether it feels safe that way.
B.B.
Is anyone interested in a 1925 diana mod 45 bb gun the gun still shoots very good but has some rust pitting

Wow this is all strange to me. So here goes. I can only guess it was around 1975 when i found this old rusted pellet rifle in a barn we were tearing down. At the time I was building black powder guns and learning how to blue and refinish so thought what a perfect gun to practice on. Well long story shortened , got married, divorced remarried and forgot about it. Now the grandson is getting into shooting so i found the old thing and discovered it is actually a Diana mod. 25. it is in as bad a shape as i found it on the outside. I did have the sense to oil it down b efore putting it away though. so now I am wondering if it is worth rebuilding and how to find parts. Never would have found anything without internet. Is there any help out there?
Thanks,
Dennis
Dennis,
If your rifle is rusted on the inside, it is probably lost. But if not, it can be rebuilt easily.
You can make a leather piston seal and breech seal from a leather belt. You can buy a mainspring from this source.
He probably can sell you the piston seal and breech seal as well.
Here is how to make the leather piston seal:
/blog/2007/12/how-to-make-a-leather-piston-seal/
The leather breech seal is so easy to make that it doesn’t require instructions. But here is some information on that, as well:
/blog/2009/1/diana-27-part-3/
Yes, it is worth rebuilding the rifle.
B.B.
Hi BB,
Thank you for a great site and a valuable resource. I used to have a RWS Diana Model 27 .22 caliber, open iron ‘U’ rear sight with a wedge type unprotected blade foresight, back when I was in my teens. This was given to me by a friend of my dad (they were both officers in the army). That rifle went everywhere with me, even to bed! And you are absolutely right – it was deadly accurate! I got so proficient with it I could actually take out birds on the wing, since I knew the pellet travel time to the target – usually 30-40 yards.
I remember the first time I took it apart to clean it, and springs, ballbearings and metal tubes flew all over the place, but I managed to figure out how it all fit together. Sadly, I had to leave it behind when I moved, but only hope the guys I left it with were able to take care of it.
I am now waiting for delivery of another Model 27, but in .177 caliber, and cannot wait to see if it is as I remember.
Again, thank you for this great site and all the historical information about this great little rifle. It rocks!!!

I bought a Diana Model 25A when I was in the Army in Germany back in 1983. I was 31 at the time. Now, 31 years later, it still shoots great and doesn’t seem to have lost any power. It has bagged a couple of bunnies and chased off some crows and buzzards that I didn’t want hanging around. At 25 yards I can shoot tighter groups with it than with my .22-Long Rifle caliber Henry rifle, which is saying something. It is SO MUCH BETTER than the Chinese-made crap being sold under recognized names such as Crosman or Beeman.
Robert,

Hello All,
Great thread on the Winchester 425 / Diana 25. I have a circa 1970 Winchester 425 that is in need of a new rear sight. While enjoying the kids plinking on targets, I turned my back on one of them leaned it up against the patio table, fell over and the V notch rear sight broke in two pieces. If anyone has parts available for either model above, I’d be interested in a purchase. Love, love this air gun and has much sentimental value to me.
Regards
Mike
Mike,
Few people see this old post. This man might have the parts you need:
B.B.
Many thanks BB. I have a European contact that may be able to source Diana parts.
I live in Germany and I just picked up a model 25. It looks like a .177 cal. At a flea market. I’m pretty excited to shoot it with my daughter. I guess it’s really designed for pellets, seems like a BB would fall down the barrel. It’s pretty rusty on the outer surfaces but the barrel looks clean.
Should I not buy BB s for it? And where do I put the oil? I don’t know what year is is either, has no ring over the front sight and says made in Germany , not west Germany.
Max,
Welcome to the blog! You can also ask these questions on our current blog page, where over 100,000 readers will see it.
/blog//
Yes, your model 25 is designed for lead pellets — not for BBs. You might start with some .177 RWS Meisterkugeln. They are a good target pellet for informal shooting.
Oil goes into the air transfer port. When the barrel is broken open, the transfer port is the hole in the spring tube that aligns with the barrel when it is closed. Use 5-10 drops of household oil (3-in-One is one brand), but any hardware or automotive store should have small cans of oil for household applications (door hinges and such).
After you put the oil in, work the piston up and down by partially breaking the barrel, but don’t cock the rifle. As the barrel comes up to the closed position, listen for a squishing sound. That will tell you that you have a leather piston seal, and that the oil is softening it. Because your rifle says Germany and not West Germany (or Germany West), I think it may have been made before the war.
It may not have rifling. If that is the case it will be accurate to about 10 meters, but not as far as 20 meters. By accurate I mean able to hit a one Euro coin 10 times in a row, when shooting from a rest.
If your rifle does not have the two screws ahead of the trigger, as shown above, it may be a simpler model 25. I wrote about a pre-war smoothbore 25 here:
/blog/2013/03/diana-25-smoothbore-pellet-gun-part-5/
Congratulations on a wonderful find!
B.B.
Hi , I recently came by a Gecado model 25 made in Germany in .22 cal. It does not have an adjustable trigger but otherwise is identical to the Diana 25 / Winchester 425 photos . Would anyone hazard a guess as to the age of this gun ? The serial number is 1413.
Gaz
Garry,
Dianas often have a date stamp on the spring tube, on the left rear, just above the wood line.
Because it’s Gecado from Geco I’m going to say it’s post-war and perhaps the 1960s 0r 70s.
B.B.
I have a Diana Mod 25 and am trying to determine the year it was made. It does not have any trigger adjustment. It has the early model rear sight. It is stamped “Made in Germany” on the spring tube. There is no date stamped on the stock. The trigger guard does not have a hole in it.
I am looking for a foresight for it.
Thanks!
Wayne,
Without seeing the gun I can’t narrow it down more than a range from 1933-1986.

Hello BB
Thanks for all the articles about Diana guns, i learned a lot and they are much better now.
I just have a problem with our 25D trigger.
It has the double screws, but it changed recently, its no longer a long first stage, but it is when i cock it, and it setts itselff, it stays up front, nofirst stage. I managed to get the release which didnt fire, to normal firin by adjusting the second screw. But what i tried it still is stuck, and i have a feeling something inside has changed? But it still shoots like a dream. Crisp release but no first stage.
Does this ring a bell?
Thanks from the Netherlands
Dennis
Ps i find a lot of old ones, even the first models but i’m not super interested, if you know folks i can send them de links?
Dennis,
Okay, that first screw is to lock the setting after the rear screw has been adjusted. Here is what I recommend. Loosen the first screw. Then run the back screw all the way in. The rifle should not cock. Now unscrew the back screw a half tun at a time until the rifle cocks. When it does, evaluate the trigger pull. If you want more first stage, unscrew that back screw more until the trigger seems fine. When it seems fine, run the first screw in as far as it will go to lock the setting in place.
I can’t think of anything inside the gun that would cause the trigger to function the way you describe. I think it just wore itself out of adjustment.

Thank you very much sir! For the quick reply and the trust you send with it. I’m able to fix them myself now since i found this blog.
I tried your method, and it worked! My second screw needs to be almost in to get the release you describe. Now it has a nice first stage again and a beautiful crisp release I guess it worked itself outwards. Strange thing is, it happend all of a sudden, and not gradually. I have to mention i hadnt been shot in a while.
But now re olied and cleaned and adjusted a bit it shoots like new.
Thanks again for the help.
Your help keeps me and my woman happy shooters.
Dennis
Dennis,
I’m glad it worked! 🙂

Me too BB!
We live in Holland and have 4 Diana’s. Mostly because of your writings. I could buy a 34 here for a good price in mint condition, so i googled and found this blog. Cos i was an airrifle dummy. And i noticed your love for the 27. And sure i came along one, so now we have 2 😉 cos they live upto the mythe. And my woman liked her own. And we have a 25d wich is great as well. The oiling really does the trick. So nice to use them and they are older then we 🙂 Thanks again and happy greetings from overseas.
Dennis,
Greetings from Texas. I am so glad that you have found the old Dianas. Now YOU know and can help spread the word to your fellow airgunners. 🙂

I will, the airgunner community is great. Friendly folks all over. We’re collecting the smaller Diana’s to share with church kids the fun of shooting. And me love to revive those old beauties. So another question, i tried to get my 27 as crisp as the 25 from above. But its weird. It has a longgg first stage superlight, and a tiny stop en it fires. But when i adjust the screw very minute, it changes so quickly. First stage almost gone, and the first few pulls stiff and not smooth and then it goes unexpectedly. My thought was maybe there’s old grease inside? Today i will try again. Thanks for your time, and again hello from Holland.
Dennis,
I’m having the same problem with the Diana 27S that I’m working on. Maybe we will discover the reason together?

Haha thats funny, but yes. I’ll keep you posted on my progress. And i can ask around on a forum in german, maybe they have an answer. Hope you have a good weekend, and take care. Greets Dennis
I have a Diana 25 Made in great Britain. I got it in the 1950s but I haven’t shot it and probably 50 years. What should I do before shooting it?
Allen,
Stand the rifle upright and drop about 10 drops of household oil (3 in One) down the muzzle. Let the rifle stand up0right for a day. Then cocking and load it and shoot it. The oil should refresh the leather piston seal.
