*You can pull back the rear part of the slide to shoot the gun single-action, however Umarex lists this gun as double-action only.

The manufacturer states that the M&P 45's velocity is 370 fps. A recent velocity test showed that BBs delivered 360 fps and pellets 350 fps.

The owner's manual says the gun is 7.10" long. That's a typo. It's really 8.10" long.


The S&W M&P (military & police) air pistol is a dead-ringer for the firearm handgun made by Smith & Wesson. If you like to use airguns to gain or retain proficiency for your firearms, this will help you do that. While the firearm will have more recoil, you'll still be able to get the feel of the gun, the weight, the handling characteristics...and more from shooting the air pistol version. With the included safety glasses, ammo and CO2, you're ready to go the minute this package arrives!

Shoot either steel BBs or lead pellets with this CO2 gun.

Things I liked: Gun fits the hand well with a comfortable heft. Gun can be fairly accurate.

Things I would have changed: Double action trigger pull is distracting... you can control your shooting once you get used to how much pressure is needed to shoot. Nonetheless, its not fun enduring it.

What others should know: Using single action makes the trigger function pleasantly, but its so distracting moving my hand off my grip to pull the slide back---especially when I get on target and are ready to begin some serious drilling of the target's center.

Things I liked: Very nice looking replica. Authentic size and trades. Adjustable rear sight. Picatinny rail under the barrel. CO2 loading system is very tidy giving the gun an authentic appearance following the contour lines of the pistol. Ability to rack the rear portion of the slide to put the gun in SA mode is really cool. Shooting either pellets or bbs makes for a versatile pistol. Recessed barrel gives an authentic look at the muzzle.

Things I would have changed: I would have liked to see the slide made of metal for a more authentic appearance.

What others should know: This is a great gun for the money. Well worth it if you like a versatile, accurate, fun pistol. For under $100 it is definitely in the top 10 in the category.
