This BB gun is a replica pistol based on the S&W Military and Police firearm. The M&P air pistol is a BB repeater powered by one 12g CO2 cylinder that hides in the grip of the BB pistol. An integrated accessory rail underneath the muzzle is a great place to add a tactical flashlight or an air gun laser. An element of realism is added with a 19-shot drop out BB magazine. The Smith & Wesson M&P CO2 pistol has a manual safety, double action trigger that's amazingly close to the actual handgun, and fixed front and rear fiber optic sights. This BB replica is not only a great BB gun for some fun plinking, but also makes a great target shooting and training pistol for S&W M&P firearm owners.

The only pro is the shipping time

Did not work when it came, it got here fast though I asked for a refund but never heard anything back.

By Shane December 4, 2020

The pistol is 430 FPS. I went to the store to buy one and it's right on the front of the package.

By FrancisNovember 8, 2020

the pistol lacks the weight and ''feel ofthe original

the illuminated sights are a great help for plinkiing. the magazine is rugged and vertually unbreakable. the pistol is good for plinking overall. it's light weight makes it easy to carry. this would be a great gift for a teen age gun enthusiest.

the plastic is too shiny; it makes the pistol look like a toy. my magazine got stuck several times, but i was able to remove it without any damage so far.

By JosephUSAApril 18, 2020

I am surprised at how powerful and accurate this pistol is at 20 yards. I am having a lot of fun with it.

Great feeling pistol. The magazine is hight quality. The sights are fantastic. Looks great as well.

The trigger is "ok". Replacing CO2 cartridges is some what difficult because of the tight spacing. Loading the clip is weird at first but once you get used to it it's fine.

By JohnUSASeptember 22, 2017

My son has one of these haha one of many he carries in his kayak been under water an still shoots very reliable little pistol



By SonnyJuly 27, 2017

Fun target pistol, accuracy so-so, but adding a red dot finder made a big difference.

By BradleyUSAJune 20, 2017

Bought this for my nephew to learn gun safety and shooting safety, even though theres no blowback it still is an excellent shooter. like the fell of the pistol, seems to have pretty good accuracy. Very enjoyable to shoot, nice to have more power and get more shots per CO2 compared to a blowback pistol. Does feel a little cheap at first but is very durable, the CO2 is easy to load, the magazines are easy to load especially compared to my Walther cp99. Seems to have a decent trigger, all in all a nice pistol.

seems durable, easy load magazine, nice trigger


By StevenUSAJune 8, 2017

I have several other Airguns, tnen after one of the fellows I worked with got his S&W 9mm, as I looked at it and handled it, I was very impressed with it. Then I saw this one and thought even though I don't need it, the price was worth the money, I ordered it as I had just given my other BB pistol to my wife. I look forward to playing with it.

Look I liked the look

A little light weight. Should be a bit heavier, I realize it is not all metal, and was going to be light.. I will add some weight. I did not care for the way the molded pieces appear in the Dark Earth color, so I will paint them to my taste. Not a problem, it is what I expected.

By MichaelUSASeptember 15, 2016

I found that this gun exceeded all my expectations for $39.95 it performed better than some guns that cost two or three times as much. I had no jam ups ,The power is pretty good I loved the two tone color COMBO.


I didn't have any

By JohnUSAJune 21, 2016

I have many air guns, but when I just want to shoot some cans for relaxation or stress relief, I invariably reach for the mp40. There are no bells and whistles, but at 10 yards I rarely miss a can, and don't have to fiddle around with the gun.... Just fire away. The S&W logo means quality, even in their least expensive airgun. In fact this one convinced me to get rid of all my 'no name' cheap air guns.

asked Jamal from USA

asked Steven from USA

Is the S&W MP40 air pistol supposed to cock to load or is that just for looks because I can't cock it back. I was figuring that it's not supposed to and that it's ready to fire after loading. Is this correct or did I buy a dud?

Scott from USA

Where can you send this gun to be repaired?

asked thomas from USA

I bought this gun about a year ago and up until now had no problems at all. Now gas leaks out the barrel and I don't know how to fix it,the gun still shoots because the leak is slow but it is aggravating to hear it leaking. Any suggestions?

asked thomas from USA

I use a small piece of Teflon tape, typically used for plumbing, placed over the CO2 cartridge, works great.


does it come with a dot sight

asked sean

Package includes: S&W M&P 40 and one 15 round magazine.

Scott from USA

I have one of these and the gas cylinder will not seal. Any recommendations? Ron

asked Ron

Are you sure the piercing knob was turned all the way in?



asked eros

No this does not have blow back action

Scott from USA

My magazine will no longer seat, it got stuck, and when I finally got it out, it wouldn't re-seat. Any suggestions?

asked Pat

Is it a blowback pistol? I really like the look of this gun and its cheap too :) I will buy it if its a blowback, please respond to this fast!

asked Mark from USA

Sorry, no blowback.

W. Scott from USA

No, it's not a blowback.

Robert from USA

is it blowback?

asked landon

No this is not a blowback air pistol.

Steve from USA

can a 12 year own this gun , and also is the 6000 BBs compatible with this gun ?

asked Pat

The ownership of a BB gun is a matter for the parents or guardian of the child to decide. Yes, the Crosman 6000 count bb pack would work with this gun.

Steve from USA

how do i get the bbs in the chamber?

asked william klick

After taking the magazine out of the gun, pull the spring back in the magazine until it locks in place, load the bb's into the circular hole in the magazine, release the spring by sliding the pin on the bottom of the magazine forward, load magaine into gun. Make sure you have a CO2 cartridge in gun, you should be good to go.


where can I get additional clips?

asked John from USA

Beretta Elite II and S&W M&P 40 spare Magazines (2-Pack)

Steve from USA

If not from Airgun Depot here, check the manufacturer.


I think i either tore the seal on my S&W or something because every time i put it a cartridge, all the air rushes out in this white cloud substance. should i buy pellgun oil or a new seal?

asked Alex from USA

what type of BB's does it use plastic BB's or metal BB's

asked Tino Conceicao

Plastic airsoft bb's won't fit in this, use only .177 bb's in this.


It uses steel bbs. This is not a airsoft gun. Hope that helps.
