The shape, weight and function of the Smith & Wesson M&P 40 by Umarex has all the similarity of the live-fire handgun. It's outfitted with a polymer chassis, superior ergonomics and textured grips. The sights are low-profile three-dot-style. The front sight is dovetail mounted and adjustable for windage. An under-barrel Picatinny rail makes it optic-ready.

I like it
May 10, 2019
Decent pistol, reasonably accurate, fun to shoot.
ProsI like this better than my Crossman Vigilante. Very solid, great action, extremely realistic copy, feels right. Fairly loud, which I like but could be a negative for others.
ConsI get 35-40 shots from a CO2 canister, 40 is absolutely tops. So it?s a canister hog, that?s not quite 3 loads of BBs and your done. Loosely translated, about every 5 minutes you have to change CO2. Also when I got it, new out of the box, the slide catch jammed immediately. Had to take the pins out, fully disassemble, and reassemble from the start. Fortunately a YouTube video had the problem and showed how to deal with it. Umarex customer service failed completely, taking the IT equivalent of ?did you plug in the machine?.
Best UsesJust having some fun in the back yard. It?s not powerful enough to shoot at rodents.

EXCELLENT training tool.
April 2, 2018
I carry an M&P 9C, and this BB pistol is perfect for VERY inexpensive close combat training.
The weight and action is so very close to my 9C that I can comfortably practice draw and stance that carry's over to range work.

Now, it'd be PERFECT but for the below issue which is YUGE ..... hopefully it will be addressed.....

After 4 cartridge loads, the mags started loosing pressure EXCESSIVELY during the piercing process.
Seems like the seal had compressed and did not retain it's sealing density.
Have recently returned for exchange. Hopefully the exchanged will be positive.
ProsVERY closely resembles my carry gun, M&P9c
ConsThe magazine / cO2 pressure issue as described above.
Best UsesRealistic close combat training...

Nice little handy pistol. Great weight compare to 1911 or 92fs.
ProsThree white dot sights, blowback action, full metal mag, rail system, light trigger...
ConsThe build quality can be better.

Excellent Training Aid
September 14, 2017
Bought a refurbished one for training as I carry the real thing (in 9mm). Its so close in look, weight, and feel that one could confuse it for the real deal in a stressful situation. I added a strip of bright blue tape to the slide for this reason and will not store the two in the same place. Fits perfect in my holsters, though it is slightly thinner than a real M&P. Will be buying an extra mag soon for mag change training. Blowback is smooth and is enough to simulate fairly realistic recoil. If you have a real M&P, do yourself a favor and buy this air gun; can't beat the training seeing as ammo and range time is so expensive.
ProsGreat construction Realistic mag capacity Nice blowback
ConsNone so far

Possibly the best !

I found this pistol to be special enough to get it its own leather shoulder holster ---- no other pistol goes into this holster !!
ProsNear-perfect replica of actual S&W MP40 in weight, design etc. Feels great in the hand & option of three grips covers most, if not all, hand types. Powerful, yet more economical, than other full-blowback pistols. White dotted sights (3), all-metal drop-out magazine & well-balanced weight distribution makes this my favorite/best pistol 'most' of the time !!
ConsAs with all types of CO2 / BB-filled drop-out magazines, care has to be given in not screwing on plug too tightly. Even then, it doesn't guarantee that a magazine will make it to the 30-day warranty. I'm not a beginner, so I make sure to take care in loading my CO2 into the magazine. I wish they would make the plugs in brass instead of rubber/plastic. If you're a daily shooter like I am, those plugs begin to wear when tightening & may stay stuck in the mag due to loss of threading.

Great product for training

Weight, fell and action are all great. It isn't too loud but allows for much more realistic training.
It is really accurate and built well.

I really enjoy this pistol. Nice blowback. Very realistic look. Easy to load. Good accuracy. Great for target shooting and/or plinking.
ProsNice blowback. Very realistic look. Easy to load. Good accuracy.
ConsTricky to field strip. Easy to get apart, but a little tricky getting back together.
By Sean
Best one of 5 different one I have
September 3, 2016
This thing is as close to the real deal as possible. The gun comes with three different size gribs which is great for teaching firearm safety. The co2 goes into the slide in clip which can hold up to 18 bbs. With this comes longer reload times for BB and co2. Other than that it's well worth the money. I might get another....

Very nice experience! The attention to detail is AWSOME!! It is by far coming one my favorite air guns. This replica is made after the Smith & Wesson M&P (Military and Police)which is a polymer-framed, short recoil operated, locked breech semi-automatic pistol introduced in the summer of 2005 by the American company Smith & Wesson. It uses a Browning-type locking system. While targeted at law enforcement agencies.
Also I own the Smith & Wesson M&P 9mm. I like to use this for training and practice.
ProsThe experience is almost exactly like the real thing except not as hard as the real thing on recoil.
ConsIt does use some of the CO2 for the blowback feature, so the CO2 wont last as long.

As close your gonna get to a real one
June 8, 2016
This is handgun is really impressive and the action is sharp and clean, i shot this right of out of the box and i placed the medium grip ( since it comes with 3 ) and it has a great feel like the real one, over all its very impressive, it dose lock back just like the actual when you shoot the last bb and place another mag and its ready to go and its really cool that it can be field stripped and be lubed if necessary, overall this is my favorite bb gun and the blowback is strong, and the trigger pull is smooth with a nice creep. I would buy at least 2 more mags if anything else, over all this is as close as your gonna get to a real smith and wesson handgun.
Prosgreat blowback, field strippable, 3 different grips for comfort, great trainer for a future Smith and Wesson M&P owner, locks back at the last round fired, and VERY realistic weight and feel. defiantly great to save money by just pennies a shot instead of spending money on .40 ammo and just shoot bbs to have the fun.
ConsThe only thing that is sorta downfall is a visible seam on the grip do to the synthetic body and the "Warning" kinda took its authentic look away but as they say " better to be safe than sorry " overall not much to complain about.
