Colt’s 1911 Special Combat BB pistol is a knockout for looks!
Wow! Today’s test is as different as any I’ve done! This air pistol surprised me completely, with results I’ve never before seen from any airgun.
The Colt 1911 Special Combat pistol shoots BBs, so a velocity test is going to be pretty humdrum. There are a limited number of different BBs to try, and they aren’t going to give fantastically different results like lead pellets do. So, usually a velocity test with a BB gun is a no-brainer for me. Shoot and record the numbers — plain and simple. But not today.
Both single-action and double-action
This pistol fires in both the single-action and double-action modes. For you newcomers, single-action is where the trigger performs the single functon of releasing the hammer to fire the gun. You have to manually cock the hammer before each shot — the trigger doesn’t do it.
Double-action, in contrast, is where the trigger both cocks the hammer and releases it, all in one smooth pull. So you just keep on pulling the trigger. As long as there’s ammunition, the gun keeps on firing.
Because the trigger is doing more for double-action, it’s always harder to pull in that mode than it is for single-action. So a semiautomatic pistol that has single-action operation will normally have the very best trigger possible. If a gun functions in either single- or double-action like most revolvers, the single-action mode will give the best trigger-pull. The double-action mode is reserved for when you want to fire a lot of rounds very fast.
There’s more to it than that, of course. Some semiautomatic pistols such as the Beretta M92/M9 fire either single- or double-action; but when they fire, the slide comes back and cocks the gun for the next shot. These guns are quick to fire the first shot, since you can carry them with a round chambered and just pull the trigger to get them started. They also have the advantage of switching over to single-action once they begin firing.
At any rate, when I have a CO2 pistol that’s both single- and double-action, I test it for velocity both ways. That often gives results that favor the velocity on one or the other of the two modes. But this gun was vastly different. It varies by about 100 feet per second greater velocity in the single-action mode. And there’s even more to report, so read my results carefully.
Single-action
I started out shooting the pistol with Daisy zinc-plated BBs in the single-action mode. The gun is rated to shoot at 400 f.p.s., so I expected something in that neighborhood; with BBs, there isn’t much variation between brands. So, I was surprised to see the first shot on a fresh CO2 cartridge register only 205 f.p.s. But sometimes pneumatics and CO2 guns need to “wake up” when they first start shooting after a rest, so I kept on shooting and watching the chronograph. The next shot went 203 f.p.s., but the one after that went 334, then 345, then 366 f.p.s. That last shot was as high as the pistol wanted to go.
My first good string of shots on single-action averaged 363 f.p.s., with a low of 360 and a high of 375 f.p.s. That’s good consistency, after the valve had woken up. I figured shooting the gun on double-action would give similar numbers. Guess again!
On double-action with the same Daisy zinc-plated BBs, the velocity averaged 252 f.p.s. The low was 224 and the high was 280 f.p.s. What a spread, and what a difference from single-action. Next, I shot two more shots single-action to see what had happened, if anything. They went 337 and 321 f.p.s., respectively. The gun was shooting slower, but it was still much faster in the single-action mode.
I then tried the RWS Match BBs that Pyramyd AIR doesn’t carry. I’ve found them as accurate and precise as Daisy BBs, and sometimes they give slightly different results. This time in single-action, they averaged 319 f.p.s. with a spread from 280 to 344 f.p.s. In double-action, they averaged 240 f.p.s. with a spread from 227 to 250 f.p.s. And shooting single-action immediately following the double-action string gave me two shots at 324 and 302 f.p.s., respectively.
I was concerned that the pistol seemed to be running out of CO2, so I fired it 20 more shots double-action with no BBs in the magazine, then I fired another shot single-action (with the RWS BBs) that went 321 f.p.s. So, it wasn’t out of gas just yet!
How many shots per cartridge?
At this point in the test there were 63 shots on the cartridge. I fired another 10 blank (no BB) shots double-action and then fired an RWS BB single-action that registered 335 f.p.s. At 84 shots, the gun is still going strong.
I next shot a single Daisy BB on single-action to see if there was still such a difference between the two brands. This one went 327 f.p.s., so both BBs are going about the same speed. The initial string of Daisys was just a little faster for some reason.
I shot another 10 blank shots double-action and then an RWS BB at 327 f.p.s. So, at 96 shots, the CO2 cartridge is still going strong. Then another 10 blank shots, followed by a Daisy BB at 323 f.p.s. That was shot number 107 on the cartridge.
Another 10 blanks shots were fired double-action and then an RWS BB went 331 f.p.s. That was shot 118. Then another 10 blanks, followed by a Daisy BB that failed to register. Then a second Daisy BB went 325 f.p.s. for shot 130. Then another 10 blank shots were followed by shot 141 — an RWS BB at 321 f.p.s.
My gosh — this pistol is starting to remind me of the AirForce Talon SS using the Micro-Meter tank! Another 6 blanks were fired and then the remaining gas spontaneously released from the cartridge. All gas was exhausted, and it was all over. This cartridge had maintained its velocity down to almost the end of the CO2 charge — something I’ve not seen in a long time. For the record, I got a good 140 shots from a single cartridge.
What about the large velocity variation at the beginning of the test? I think we can chalk that up to the gun breaking in. After several hundred shots have been fired, I think the gun will perform more consistently; but I’ll come back in a special test, after we look at accuracy, and rerun the velocity test again.
Trigger-pull
The double-action trigger-pull broke at an average 10 lbs., 6 oz. of effort. The range went from 9 lbs., 6 oz. to 11 lbs., 5 oz. The faster the trigger was pulled, the lighter it became. The pull effort increases rapidly (stacks) the further back the trigger is pulled.
The single-action pull was a very consistent 3 lbs., 7 oz. The second stage is very apparent (I mean there’s a definite hesitation of the trigger blade at the start of stage two), and there’s just a hint of creep in the second stage.
So far, this ranks as a very interesting BB pistol. The test pistol fell short of the advertised velocity, but delivered a huge number of good shots from a cartridge. I think the way it turned out was better than if the velocity had been higher and the shot count less, because high-velocity in a BB gun is about the worst thing you can have. Given the tendency for BBs to rebound with great speed, you really don’t want them going too fast.
Accuracy testing is next.
While you state the “blanks” were done double-action, it’s not quite clear if the velocity measurements were then all single-action. I’ll presume they all were single action since you did state that on the first of the set.
Regarding the velocity difference between single and double action. If this model actually uses the falling hammer to open the valve, I can understand a difference — since a double-action hammer typically releases at around 75% of the full (single-action) cocking point, it probably hits the valve with less force.
I’m tempted to confound the neo’s with the expansion on your single vs double action semi-autos… by mentioning models that are double-action only, and some that are in-between (usually internal striker models in which the cycling of the slide only partially cocks the striker or even stranger behavior*).
* The wikipedia article isn’t quite accurate for the first generation Walther P99… Chambering the first round does cock the striker while leaving the trigger forward, but that is not a double-action trigger pull — it’s more of a long stroke single-action pull. Only if one chambers a round and THEN presses the decocking lever to release the striker does one get a full double-action pull
Wulfraed,
I left out the reference to a single-action pull when testing the BBs because I thought it was obvious from the velocity realized. In retrospect, I should have mentioned it the first time.
B.B.
Well, given that I was replying at 1AM, I probably wasn’t the most tactful…
Just a follow-up to my first-gen P99 comment.
Pulled the magazine and emptied the chamber to test…
If decocker had been pressed after cycling the slide, one has a long double-action pull
If on cycles the slide with the trigger back (emulating the autoload after firing a round), one can reset the trigger with a very short forward motion — close to normal single-action pull
BUT: if one completely releases the trigger after the slide has cycled (or cycle the slide to load the first round of a magazine, with the finger off the trigger), the trigger moves forward to where it has a double-action length, but the first half or so is just trigger return spring… Sort of a two-stage trigger pull.
What I think the wikipedia article referred to as “AS” (anti-stress) trigger in the second generation. “Anti-stress”, in this situation, does not mean the shooter will be more relaxed, but rather that having the longer initial single-action pull makes it less likely a stressed out shooter will accidentally fire the pistol (especially if it is carried in a cocked-striker condition; there are no manually activated safeties — decocker [leaving heavy double-action pull], long-stroke/two-stage single-action on cocked striker, and a trigger linkage safety [but that only blocks something if there is no pressure on the trigger itself])
If I was interested in CO2 action pistols, this one is definitely shaping up to be a real nice one to have. It is obviously far superior in performance so far from almost all of the competition. I will bet it does pretty good in the accuracy department also.
While it could still crash and burn, it’s looking good so far. It could turn out to be a good plinker and practice pistol.

I said I wasn’t buying another 1911 after the awesome Tanfoglio Witness but I’m now having second tought…
J-F
I have to say. That colt looks awesome. Except for that retarded looking trigger.lol
Well retarded looking trigger for a 1911
My Mom just asked about a bb gun to play around the house with… This reminds me of the saga of my Walther Nighthawk. After shooting it for years and struggling sometimes with the trigger, the trigger seemed to stop working all together. I had to apply something like 40 pounds of force. B.B. suggested that I switch ammo which I did from RWS Hobbys to a Crosman pellet. The trigger pull changed dramatically–a clear case of how a pellet can change performance. But I couldn’t hit anything. I persevered but finally decided to try a clip of RWS Hobbys. I immediately got back all my accuracy, and the trigger was no worse than with the Crosmans. So I’m back to where I started. I must have had a bad batch of Hobbys.
Edith, thanks I understand now. The old double-blind trials. What threw me off was the comments on the PA site where Gene and Boris said that they would trash the other; just a bit of competitive spirit I suppose.
Desertdweller, focusing on my shot sounds easier than focusing while plunging around a track. As it says about Mad Max: “the lightning reflexes and the merciless concentration that made him the best driver in the Pursuit Force.”

Matt61,
Trash talk is part of competition 🙂

Noticed on the dashboard of a stock car: “When the green flag drops, the B.S. stops.”

Went to the shooting range today with Melanie, but it was too hot to spend more than a half hour.
We took turns shooting my new PPK/S and my wife’s Gamo P-23. We tried both pellets and bb’s in the Gamo.
The new PPK/S is not as accurate as my old one, but shot pretty well for a brand new gun. We were shooting Crosman Copperhead bb’s in both guns, and Cabela’s 7.9 gr. wadcutter pellets in the P-23.
The Gamo was much more accurate, especially when firing pellets. I was able to hit the target backing board at 50 yards with the Gamo shooting pellets.
Melanie found both pistols easier to shoot than the Daisy 15XT. She did well, but I want to keep her on pistols for a while yet until her face completely heals inside.
The same day I got my new PPK/S from Pyramyd AIR (last Monday), I got a new air valve assembly for my old PPK/S from Umarex. I managed to destroy the new valve installing it, so had to order yet another one. My wife thought it was funny…
Of course, I turned down the offer from Unmarex to fix the gun for me if I sent it to them. That is “Plan C”.
Les
BB, any opinion on Winchester flatnose pellets?
Guest,
Since they carry the Winchester brand, they are probably sourced by Daisy. That means they are either from Spain (average) or China (worse than average).
I have not tested them yet.
B.B.
I waiting for mine to come”I orderedf the pkg. deal It sure looks good and the review
seemed positive.Time will tell if it turnd outgood I’ll get anotherI have the Unarex Colt
which costs three times as much and in stainless it is beautiful”I don’t expect it to
be in that league.
