## Description

The Smith & Wesson M&P is a favorite of law enforcemen. The M&P air pistol is a BB repeater powered by one 12g CO2 cylinder in the grip. An integrated accessory rail makes adding a tactical light or laser easy. The 19-shot mag drops free. The M&P has a manual safety, double action trigger, and fiber optic sights. This BB replica is not only a great BB gun for plinking, but it makes a great target shooting and training pistol for S&W M&P owners.

Review: So realistic its scary! - I picked up the Umarex Smith & Wesson M&P 40 .177 Caliber BB pistol mainly for backyard target practice and training, and it has honestly exceeded my expectations for a CO2 air pistol in this price range. The first thing I noticed was how realistic it feels in the hand. The weight, grip texture, and overall design give it a solid feel that’s much closer to the real firearm than a typical cheap BB gun. The blowback action adds a lot to the experience and makes shooting more enjoyable. Recoil obviously isn’t the same as a real handgun, but it gives enough feedback to make practice feel more realistic. Accuracy has also been surprisingly good for casual target shooting. At reasonable backyard distances, it consistently grouped shots well once I got used to the sights. CO2 efficiency has been decent so far, and loading BBs into the magazine is straightforward. The trigger pull is smoother than I expected, although there’s still a little stiffness during the first few uses. Build quality overall feels durable, especially the slide and frame fitment. What I like most is that it’s a fun and affordable way to practice handling, sight alignment, and trigger control without spending money on range trips and ammo. Just make sure to use proper eye protection and safe shooting practices because this thing definitely has enough power for serious target use. Overall, this is a great choice for anyone wanting a realistic-feeling BB pistol for training, plinking, or recreational shooting. Solid performance, good build quality, and a lot of fun to use.
Review: Lots of fun - Simple and so far good. This does look real so treat it that way! Not for unsupervised kids! I give five stars because of price and function. This is basically a dangerous toy. It’s probably strong enough to cause serious injury or death to small animals. I would not recommend trying to use it for that however because it’s not really high enough power to assure efficacy for hunting purposes. It’s lots of fun for backyard plinking at targets and cans. It’s fairly accurate for a smooth bore BB gun. Holds 19 shots max and the only malfunction we had was when we tried fitting to many in the magazine, I have two adult sons that played with it for hours (800) rounds so far and 4 cO2 cartridges. BB’s ricochet so think about safety glasses and a softer backstop. “You’ll shoot your eye out!”

## Questions & Answers

**Q: Plastic or Metal BBs????**
A: Metal.  I prefer the silver (zinc plated) Daisy BBs, they don't leave residue in the barrel like the coppery Crossman ones can.

**Q: Would i be able to do airsoft battles with this or is it to powerful**
A: It's to powerful

**Q: does the slide lock**
A: You are looking for blowback, which there are BB guns that have this and the slide does lock, all the way on last shot, you just need to make sure the gun markets itself with “blowback”. I got the Glock 19x 4.5bb .177 with blowback, awesome. Amazing replica

**Q: Is there any recoil?**
A: yes heavy recoil hurts my wrist

### ⭐⭐⭐⭐ New BB magazines shoot more accurate that original factory bb clip.
*by J***S on February 8, 2025*

Update: I bought a 2 pack of replacement clips for this BB gun and now the bb gun shoots straight like it should. Most people get a good bb magazine with their purchase, but I was unlucky. The original clip still shoots bbs in all different directions, but there is nothing wrong with the bb gun. I have tried several different clips with this gun and 1 clip shoots really really accurate, 2 shoot reasonablly accurate, and the one that came with it shoots all over the place. I have changed my review from 1 star to 4 stars because I can now get it to shoot straight with the replacement clips. I am still taking off 1 star because each clip shoots different. My advice is to get extra clips and test each one for accuracy. If they shoot straight and feed correctly, keep them, but if they don't, return the ones that are not satisfactory. If you get a BB gun that doesn't shoot straight like I did, just order a 2 pack of the extra bb magazines for this gun. Note: these extra bb magazines are recommended by Amazon for this gun and they also work great in my Crosman C11 bb gun. As for the people who complain about it being hard to screw in the CO2 and the gas leaking because of the way the handle opens, try taking the handle off carefully by gently pulling one side up and it pops off and goes back on. See attached pictures and video. Original review: This has to be the most inaccurate bb gun I have ever shot. The BBs don't shoot straight out of the barrel, instead they hit up, down, right and left, basically everywhere but where I am aiming. When shooting at a circle from 12 feet away, they are hitting all around the edges of the circle, but never in the center. With my other BB guns, even if the sights are off, the BBs hit in the same place and I am able to adjust my aim and shoot the center out of the target. It does, however, shoot with great power (over 410 fps) and is easy to work and the trigger pull is nice. It even looks pretty and like a real gun. This thing is kinda worthless as a BB gun for shooting things because it will not shoot the BBs out straight. The BBs curve in all different directions, so there is no way to adjust my aim. One shot will be high, the next low, the next up and to the right and then the next one curves to the left. By far this is the most inaccurate BB gun I have ever seen, but it sure does look nice and realistic. I love the fiber optic sights, too.
