Well, it all came down to accuracy, and the Mayhem .45 Sport Tactical air pistol has it in buckets. However — and it’s a big one — the trigger is so hard to pull and it’s also double-action only that it creates a problem shooting the gun accurately. If this had a single-action trigger, I bet I could shoot half-inch groups with it — especially at 15 feet. But I’m getting ahead of the story.
The first BBs I used were the RWS BBs that I’ve mentioned in the past. They seem to group just as tightly as Daisy’s zinc-plated BBs, and I wanted to give them a chance in this pistol.
I started the test at 15 feet, and the nature of my range dictates a one-hand hold at that distance. I didn’t expect very much until seeing the BBs all go to the point of aim. However, I wasn’t able to hold the gun still enough to pull the trigger, which requires over 12 lbs. of effort, and still keep the pistol steady.
Since it shot so straight at the close distance, I decided to back up to 25 feet and try it. Normally, I don’t shoot BB pistols that far back, but at that distance I could use a barricade rest and this pistol might surprise me.
A barricade rest is a very steady hold for a handgun — especially an air pistol that doesn’t recoil. I grab onto the barricade, in this case a door jamb on my right side, with my left hand and rest my right (shooting) hand on top. Then, I lean into my hands to further steady myself. This eliminates the shakes and allows for a good arm’s-length sight picture.
The Mayhem trigger-pull is so heavy that, after the first group at 15 feet, I had to pull the trigger with my middle finger because my index finger was out of strength. The BBs also went slightly higher at 25 feet.
After this group, I reloaded the magazine with Daisy zinc-plated BBs for another try. My trigger finger was giving out at this point, so this was the last group I would be able to shoot with any accuracy.
This time, I gave it my best for 10n shots. From where I stood, every shot looked like a perfect release; but when I walked to the target, I saw that the group was more spread out. Ten shots went into 1.873 inches.
The Mayhem BB pistol has several things going for it. It gets an incredible number of shots per CO2 cartridge, yet the velocity remains high. The BB magazine is very easy to load and manage. Accuracy is also well ahead of many BB pistols.
On the down side, the sights aren’t adjustable. As we see from this test, it would have been nice if they were.
But the trigger is the biggest sticking point I had with this pistol. It’s double-action only, so there’s no possibility of relief from the excessive pull. I’m usually pretty neutral when it comes to triggers. I shoot so many airguns that I can adapt to just about anything. But this one is too much even for me. I know I could have shot better with a trigger-pull half as heavy or with a single-action pull.

Announcement: Before we begin, I want to mention a correction I’ve made to the review of the Evanix Conquest. Apparently, the dual mag is not included with the gun. It was simply sent with the gun for testing. I’ve edited the review and noted the edits. The dual mags are available for purchase.
Today, we’ll look at the power and velocity of the Mayhem .45 Sport Tactical air pistol. As you recall, this pistol is double-action only (DAO), which means the trigger retracts the striker before firing. So, the trigger-pull will never change as you shoot. It’s always going to be heavier than a single-action trigger.
Don’t confuse single-action and double-action with single-stage and two-stage. They describe entirely different things. Single-stage triggers are those that have no movement when the gun is cocked. You just pull until the gun fires. Two-stage triggers have a lighter first stage that stops at stage two, which then should break or release crisply when the gun fires.
I always learn something from every test I conduct, and this time was no different. For the first time in my experience, I found a CO2-powered BB gun that needs a short break-in! I tested the gun with Daisy zinc-plated BBs. The initial shot went just 351 f.p.s., and I was stunned to see that it was 80 f.p.s. below the advertised velocity. But the next shot went 404 f.p.s., then the third went 373 and so on throughout the first 10 shots.
I saw a high of 429 f.p.s. around shot 10, but the average was far below that number. I reloaded the stick magazine and tried again!
The second time was similar to the first. Shot one went 399 f.p.s., and then the velocity dipped as low as 384 f.p.s. Shot six then went 423 f.p.s., which was the fastest shot in the second 10-shot string that averaged 407 f.p.s.
Then, the gun started performing better and better. The average of the third string was 427. String 4 averaged 421 and on and on until the 11th string averaged 408 f.p.s. That was the final string that made over 400, but there were still about 20 more usable shots left.
Yes, this pistol gave me over 130 shots on a CO2 cartridge! It was as close as I have come to cold fusion in quite a while. I almost had to break the velocity test into two parts because the testing was taking so long. Is that music to your ears? This is the ideal air pistol for those who lament the cost of buying CO2 cartridges.
The fastest recorded shot went 435 f.p.s., so the gun seems to be right on spec. I even got used to the DAO trigger and believe I can control it during the accuracy test.
The gun doesn’t seem to need much recovery time between shots to maintain its velocity. At times I was firing as fast as a shot every 5 seconds without hurting the velocity at all.

I said in Part 1 that the magazine looked to be easier to load than most stick mags — now I can say that with confidence. The follower locks down in place positively, yet a flick of the finger releases it after the magazine is loaded.
The safety on this pistol is located on the right side of the frame and is one that requires a forward push on the milled plate to unlock the safety lever, which then moves up and down. It’s a design that requires some thought to operate, but it completely disconnects the trigger from the striker, rendering the gun incapable of firing.
Made for a silencer
The Mayhem has deep roots in the world of airsoft. One of the ways you can tell is by examining the muzzle, which is threaded for a fake silencer. While it wouldn’t change the minimal report (the gun really isn’t very loud), it will probably appeal to many shooters. I don’t know that there’s an optional silencer for this handgun — yet; but if there’s enough demand, one probably could become available in the future.
This is the ideal air pistol for those who lament the cost of buying CO2 cartridges.
All things considered to this point, the Mayhem has a lot going for it — especially the gas economy! But at the price, it’s going to come down to accuracy.

If you liked the Dan Wesson revolver we looked at a couple weeks ago, here’s another realistic airgun for you — the Mayhem .45 Sport Tactical air pistol. This one is a semiautomatic pistol style, and the owner’s manual says that it fires semiautomatically. Without a 12-gram CO2 cartridge installed, all I could feel was a double-action-only trigger-pull, because every pull of the trigger was obviously also cocking the internal striker. So I installed a cartridge to see if it really is semiautomatic once charged.
Not a semiautomatic
Indeed, this is not a semiautomatic! When you pull or squeeze the trigger, you’re also retracting the internal striker against a powerful spring. A true semiautomatic would cock this striker spring for you by the action of firing. In a firearm, the moving slide would push the external hammer back until the sear caught it and then all you would have to do is squeeze the trigger a little each time to release the sear. That is the definition of semiautomatic. The exposed hammer you see on the gun is a solid cast piece that doesn’t move, so the real striker (the correct name given to a weight that is internal and doesn’t pivot on an axis, but moves straight back and forth to impact the end of the valve stem) is inside the frame of the gun and hidden from view.
Some people insist that double-action-only applies to just revolvers, but that is incorrect. Glock sells only firearm pistols, but they label their triggers correctly as double-action-only. The Mayhem trigger is also DAO.
The Mayhem is very large and heavy. The grip feels wide — like the grip on a double-stack firearm pistol in which the cartridges in the magazine are offset to accommodate twice as many in the same magazine height.
The entire exterior of the pistol is metal except for the grip. That’s where the weight of 2.29 lbs. comes from.
The sights are the fiberoptic type that I usually criticize for their lack of precision, but this is a BB pistol and probably capable of shooting to the same precision as the sights can control. So, in this case, the sights match the capability of the gun very well. There are no adjustments for these sights. The front is a red tube that is largely unprotected from impact and the rear is a curved green tube that appears as two green dots.
The entire top of the pistol is a stylized Weaver rail that Pyramyd Air calls an optics rail. Under the muzzle, there’s also a short Picatinny rail for accessories like tactical flashlights. Weaver bases will attach to Picatinny rails, but not vice-versa.
Looking down on the top of the pistol, we see the stylistic “Weaver” sight rail that extends the length of the gun. It should accommodate standard Weaver bases, but it has non-typical scalloped notches instead of the usual square Weaver notches.
The whole plastic grip panel pulls back to expose the CO2 cartridge housing. Loading is quick and easy and the screw that tensions the CO2 cartridge does not show when the grip is forward.
The 19-shot BB magazine is a stick-type located in the front of the grip. It’s made of metal and better-made than 90 percent of the stick magazines I see in similar airguns. The spring-loaded follower pulls down and locks at the bottom so you can load the magazine with one hand. There’s a wide opening for loading the BBs. When you’re finished, push the base of the follower that protrudes through the bottom of the magazine, and it’ll unlock and spring forward to tension the BBs.
The slide doesn’t move on this gun, nor is there any blowback sensation. The trigger stacks toward the end of the pull, allowing you to control the gun for more precision. It isn’t as easy to control as a gun with a single-stage trigger, but you can learn to control this kind of trigger pretty quickly. I imagine a gun like this will be chiefly used for plinking at soda cans and targets of equal size, though I do plan to test it on bullseye targets.
The power is rated at 430 f.p.s. Since this is a steel BB gun, there can be no confusion about what that means. Only steel BBs will be used in the gun, so any that I try should go approximately that fast.
This is another air pistol that made the transition from airsoft. You can see that in several places, starting with the threaded muzzle that’s obviously meant for a silencer. A second clue are multiple references made in the owner’s manual, where the instructions refer to this as a “soft air” pistol.
There’s nothing wrong with transitioning from an airsoft gun, We saw that in the Dan Wesson revolver and liked it very much. But this pistol must stand on its own merit, so it’s going to be treated the same as all other BB pistols. As nice as it feels, I hope it does well!

Test and photos by Earl “Mac” McDonald
Today, we’ll begin a look at a brand-new übermagnum from Ruger, the Ruger Air Magnum Combo. This is another spring-piston breakbarrel with smashing power, and I can tell you where that power comes from — in a moment.
Mac described the rifle as a Diana RWS 34P on steroids. And, then it hit him. Maybe, it’s really more of a Diana RWS 350P Magnum. Regardless of what it reminds him of, the report will focus on this new rifle, only.
Now, being both a breakbarrel and powerful is going to mean one thing for sure. This rifle will take some technique to shoot well. You’ll have to apply the artillery hold and find and use the one best pellet no matter how many tins of lead sinker larvae you can find on sale at Wal-Mart. You know, praying doesn’t make bad ammo good, and no amount of savings will ever be enough to compensate for the miss you know started out as a good shot.
The rifle comes with open sights. In this case, they’re fiberoptic, front and rear, which is probably the right choice for a hunting gun. And, the rear sight is fully adjustable.
A scoped combo
Being a combo, though, the rifle also comes with a scope. In this case, it’s a 4×32 that I’m sure you’ll want to upgrade at some time, though Mac tells me the one on his test gun is pretty darned clear. It doesn’t have parallax adjustment at this price level, but Mac will share how to adjust the parallax on this scope in part three of this report. You can set it to 25 yards, if you like, and you’ll be averaged for hunting. Or, if you just want to shoot it at 10 meters (even though this is not an indoor plinker by any means), it should be possible to set it for that range.
And, some very good news. The rifle has a Weaver base permanently attached to the spring tube. So, buy Weaver rings and forget all scope mount movement problems. Of course, if you get the combo you also get a scope mount set, so there’s nothing more to buy.
The rifle is very large, Mac says, though at 8 lbs. it isn’t a heavyweight. It’s 48.5 inches long, which makes it much longer than the average breakbarrel. The length of pull is a good 14.25 inches, which most adults will find in the right range. The barrel measures 19.5 inches, which you’re going to want for some cocking leverage.
Where the power comes from
The cocking effort on Mac’s test rifle measures 58 lbs.! Yes, I said 58 lbs. If you want to know how that would be measured, look at this video. Please, think that through before you order one, because at that level of effort you’re not going to use one of these rifles for plinking. Even bodybuilder Lou Ferrigno would soon tire of that much effort. But, hunters shouldn’t care one way or the other, because they don’t have to cock their rifles that often. Umarex, which imports the gun, lists the cocking effort at 42 lbs. Even that’s substantial.
However, it isn’t just the powerful mainspring that creates the extra power of this rifle. Mac reports that the barrel also comes back about 120 degrees from closed before the rifle is cocked. That extra stroke of the piston is where the real secret of power lies. We know today that swept volume in springers is the real secret of their power, which begs the question of why the rifle has to cock at 58 lbs. Maybe it was a poor mainspring choice and maybe an aftermarket tuner can chop out 20 lbs. of effort without losing much power, but that’s not a question we’ll address in this report.
The one note Mac added about cocking is that he cannot feel the sear set when the rifle is cocked. The safety comes on automatically, but you really have to give the barrel a hard last yank to ensure the rifle is cocked. Maybe that’ll change with break-in, like the older Gamo triggers and BSF triggers used to, but we shall see.
Mac measured the two-stage trigger at 53 oz. He says stage two is a bit vague, but you can feel it. The trigger is also adjustable, but only for the length of first-stage travel.
You can see that the butt is synthetic, and Mac noted the thick, smooth buttpad. The stock design is conventional Monte Carlo style, but without a raised cheekpiece. Note the complete ambidextrous design because of where the automatic safety is placed, at the rear of the spring tube. The metal is nicely finished medium satin and sets off the dark stock perfectly.
More toys, boys!
