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.

Smith & Wesson MP40 BB Pistol Features
  • A replica of one of the newest S&W designs
  • A BB repeater powered by CO2
  • CO2 compartment in the grip
  • Integrated accessory rail
  • Removable 19-shot BB magazine
  • Manual safety
  • Fixed sights (fiber optic rear sight)
  • Dark earth brown frame

Nice shooter
June 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.
Prosseems durable, easy load magazine, nice trigger

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.
ProsLook I liked the look
ConsA 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.
Right on target"

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.

A solid basic airgun
June 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.

March 25, 2016
An excellent well-rounded pistol I shoot this everyday is well worth the money and has no Jam and no malfunctions if you are considering buying an air pistol this will be your very best option the makers at Smith & Wesson have done a very outstanding job it fires at a very high rate of speed and a very powerful shot I suggest you buy one
ProsA very powerful air pistol very realistic and very accurate making it a very good choice of money well spent
ConsAs with all the other reviews there are no cons to this pistol I do suggest buying more magazines as I will do the same I tip my hat to the manufacturers of this pistol

S&W M&P 40 CO2 BB
August 23, 2015
The pistol comes in a plain cardboard box inside a bubble wrap bag. Other than the "refurbished" printed on the box I could not distinguish this pistol from new. I have bought several refurbished guns from AGD and all were in like new condition. The pistol feels light and is plastic. This is a double action pistol so some bit of effort and trigger travel is required to fire it. This pistol is not a pistol designed for supreme accuracy. This is a pistol designed to give reasonable accuracy out to several feet for 18 or so shots just by repeatedly pulling the trigger. With the standard fixed sights at 20 feet I can hit a spoon sized object off hand more times than not. This is a fun pistol for plinking.
ProsExcellent value. Lots of shots per CO2 cartridge.
ConsDouble action only. Feels light.

Great Buy
August 20, 2015
For and overall rating I'd have to give it 5 stars. The gun feels solid and looks authentic. I bought this for fun and to give the impression that it's real for safety. As far as power and aim it's just what I hoped it would be. Once you get it and figure out how all the parts work it's very easy to change CO2 and BBs. I'd recommend it to anyone thinking about buying it.
ProsLooks real Seems solid as far as quality Great aim Easy and fun to use It can hold about 17 BBs in a clip and fires as fast as you can pull the trigger.
ConsCO2 can be a little tricky to load / replace at first until you get the hang of it. Sight isn't adjustable but it's dead on. So no need to adjust it.

Refurbished S&W MP40
August 15, 2015
Worked as new out of the (plain brown) box !

Quite powerful as well.

Felt a bit light in the handle compared to my other BB guns, but not bad overall.

Only way to know it was a refurb was a fingerprint sized white scuff mark on the black slide. I rendered it 99% invisible with a black Sharpie.

ProsPower. Price.
ConsCosmetic mark that was easily fixed.
By Raj
Bought this gun, shipped it over here to Canada. Works perfect.

Don't let the refurbished title scare you. This gun comes clean and fires perfect. Didn't leak, clip was perfect, and gun was accurate. 10/10 would reccormend.
ProsVery accurate Powerful
Conscolour is somewhat weird (it looks the same in person as the picture don't worry). ^ this is just personal preference.

Right out of the box it was accurate, powerful. Lots of shots per CO2. So many in fact that I ran out of time and had to put it away. Several weeks later, I still put several mags through it before it lost too much power. I quit shooting when it failed to penetrate an empty soda can.
ProsAccurate. Powerful. Lots of shots per CO2.
ConsBlowback would be cool

Excellent BB Gun!!!
February 11, 2013
I've owned this BB gun for over 6 months and have to say it is one of the favorite in my collection. I have the PX Storm, and several other BB/Pellet pistols, and several Gamo Rifles. I still shoot this one the most out of all of my guns. Their cheap but well made. They are a little hard to get used to at first but once you do, like I said, I prefer it to any of my others. It actually still shoots as fast as advertised and will for will over 100 rounds, and actually more like 200. Don't be put off by the cheap price; try it and see if it does not become one of your favorites.
ProsShoots as advertised and lasts a long time before having to change out the CO2 cartridge. Get extra mags because you will enjoy it enough, you won't want to have to wait to refill to shoot another magazine. Excellent price for such a dead-on pistol, and one that lasts as long as it does.
ConsNot enough positive reviews to encourage others to try them out. I really am being honest when I say I choose this over all my other BB/pellet pistols, and can't understand why nobody else is writing in.

December 11, 2012
Well it's definitely a nice gun, don't let the refurb scare you. Only four stars cause the gun is MOSTLY PLASTIC and the Co2 handle cover can be yanked off when drawing from holster, if u slip on the grab. Other than that it's pretty accurate. You get a stray round here and their just like every other BB gun, not a pellet gun with a rifled barrel so don't expect to be a surgeon. But I would buy one more cause two handed beer can killing would be flippin dope. Oh yeah and sweet color.
ProsGood feel...nice sound...nice sights...and very economical on co2.
ConsPlasticy...and lose cover...oh yeah and definitely not 480 fps

Accurate and Affordable
June 26, 2012
This gun is great! For it's price, this is a serious competitor with some high end target pistols. Although it does not have the same power and mechanics of a target pistol, the sheer accuracy of the gun itself is remarkable. The fiber optic sights working with the effective use of pressurized gas in the gun make for a great experience and a very satisfactory grouping. This gun is a must-have
Pros-Very affordable -FIBER OPTIC SIGHTS -Lightweight design and compact frame help with the overall accuracy of the gun
Cons-Not very durable -Trigger is trickier than most airguns, but one can easily get used to it
By Moosemeat

Great while it lasted
March 28, 2012
First, let me say I loved this pistol. It looks fantastic, was amazingly accurate, and had adequate power. Unfortunately, after a couple of hundred rounds, the magazine catch failed and the magazine would just fall out of the gun. I have sent it back to Airgun Depot In exchange for a Colt Defender. I have seen other reviews on the web that have identified a similar problem with this magazine design. I liked the gun so well I am thinking about ordering another. Great customer service from Airgun Depot, and it's only $25.00 after all. If this gun had held up, five stars for sure
ProsAppearance is superior. From a few feet away it looks exactly like a real pistol. Very accurate for a smoothbore BB gun. Good power. Light, but feels solid and substantial. Trigger pill is long but manageable
ConsThe magazine Safety is backwards. When you holster the gun, the safety catch is moved off safe! This is a serious design flaw. The safety should operate the other way- forward to fire, back to safe.

Great airgun
March 3, 2012
This is my second purchase through Airgun Depot on a refurbished air gun. Other than the "R" (The manufacturer stamps this on all refurbished guns) stamped on both sides I found nothing wrong with this airgun. Installed the CO2 cartridge without any problems. The magazine slides out of the grip smoothly. Others talk about the long pull of the trigger, this does not seem to be a problem with me. The fiber optic's for the sights works great. Thus far the accuracy is pretty good. Nice grouping at 10 yards, mine is shooting a little high and right but, there again it may be the shooter too. Have hit 1# coffee cans at approx. 20 yards. The magazine is easy to load the BB's. This was just the type of airgun I was looking for simple to use and accurate. I expect to have many hours of fun.
ProsLocation & operation of the safety. Fiber optic sights. Smoothness of unloading the magazine. Ease of loading the BB's Shooting accuracy
ConsThe earth brown color.

I bought this gun for my son and he absolutely loves it! It's pretty accurate at close range and the clip looks just like the one in my crossman pistol so I'm pretty sure they will interchange which is cool. Great buy, don't be hesitant about it being a refeurb.

excelent choice
January 18, 2012
This is the first air pistol that I have ever owned and I like it a lot. It is good for fun shooting and to teach my grandkids about gun safety.
ProsThe first thing was the cost and the fact that it came in like new condition.
Cons the only thing that I had a problem with was the fact that when I pulled the grip back to load a co2 cartridge I used a little too much muscle and pulled the grip off the gun,it was a little hard to get back on but if you are carefull,you should be fine.

January 15, 2012
This is a really fine little light weight plinker. It can easily and consistently knock over 1 oz. pill cups at 18feet. It performs perfectly and given some refresh time can fire off 7 clips of BBs on one CO2 cart. Trigger is long but has a stop just before firing and is easy to pull. Sighhts are tru-glow and easy to see. I found it for the money hard to beat. Mine was dead on out of the box at 15 feet.
Prossmooth trigger, for a BB gun very consistent and accurate, flawless performamnce, number of shots, light weight
Consfixed sights, maybe too light for some, grips do not slide far enough back for easy access to piercing screw.

I'm 63 and use .177 caliber air guns for plinking and varmint control. I obtained this pistol when I returned my Colt Defender BB pistol to Academy due to a major malfunction after only two C02 loads. I originally intended to get a refund but, because I like the actual S&W M&P .40 platform, decided to swap for this pistol and got a FAR better pistol in the bargain.
The M&P shoots more accurately and wastes less gas for more shots per cylinder. The C02 retains full charge for at least two weeks that I know of. No leaks. The mag is very easy to load with ammo, but loading the C02 is not because the grip is in the way, but this is not a deal breaker for me. It's not a replica with blowback or functioning replica safeties, etc., but at this price point why would one expect those amenities? It feels good in hand, the trigger pull takes some getting used to, it has some recoil (which I like very much), and it is very accurate for a smooth bore. I have lost count how many rounds I have run through the gun without the slightest issue.
This would be a great pistol at any price.
ProsGreat feel, accuracy, reliability. I have $36 in mine and I still think I got a heck of a deal, so this $25.99 sale price is crazy good.
ConsThe grip should be redesigned in future models for easier C02 reloading.

absolutely love it! it had a few minor scratches on it, but i think it adds more character to the gun! shoots just as accurate and as many times (around 250 rounds) as the new version. I have the black m&p 40(bought new) and loved it so much had to get the earth brown version as well, and figured i would save a few bucks and go with refurbished. I'm very glad i did, GREAT GUN!

Really good gun . Had it for a day so far but I have shot about a 800 rounds through it and it's still brand new . I re recommend getting extra clips although I don't have them I want them because reloading is annoying. I think this is the best gun off the site that's 40 bucks . I think I will buy another one so I can have akimbo .

3.extra CO2

the only trouble i have is putting the CO2s in. Its hard to twist the knob with the handle open.Great gun,why wait to get yours!
January 13, 2011
Even though it's refurbished it works great. My first one didnt work so i sent it back and air gun depot got me a new one and it works. Its fun to go shooting mice or birds with. You can get about 200 shots before the bbs start to drop. The only bad thing is the long trigger. Shoots good. BUY THIS PISTOL!!!!!

This performs as advertised and as the reviews attest. This gun is a lot of fun to shoot. Plenty of power and pretty accurate as well. My only "complaint" is when you slide the grip to put in the air cartridge it has a tendency to come off. As I use it more, I am more careful to move it slowly. That solved that issue. I would recommend the purchase of extra magazines.

Nice Design CO2
February 16, 2010
Refurbished S&W M&P; The first one I received had an audible leak inside the gun (even with a drop of pellgun oil). Airgun depot has excellent policy on returns, and I chose to try and replace with another identical - the second one they shipped seems fine with no leaks.
The factors I was looking for was price, BB, and easy on CO2 consumption, which seems to mean pistols with no blowback. Satisfied with Airgun Depot and also with this gun, All in all, my second refurbished was fine, only way to tell refurbished is a faint 'R' imprinted on both sides of the gun (which may be standard practice with many makers) and slight evidence of normal wear nicks etc to outside plastic that would occur after no time at all, not at all extreme, not unacceptable, not even very noticable unless under extreme close inspection.

great pistol
November 28, 2009
this is a great pistol for a low price. it works better than it should and airgun depot did a great job sending it fast. the two down sides of the pistol are that the slide dosnt move wich i wasnt sure about when i first bought it and that the barrle sticks out when you shoot it. it also has a little bit of recoile wich is nice for a non blowback. the best thing about this pistol is that it uses all the co2 it dosnt start to drop in pruesser until the last ten shots and you also get about 7 twenty shot clips off of 1 co2.
overall buy it
By Bryan
Buy it!
October 14, 2009
This things looks GREAT, is SUPER accurate, gently sips Co2, sounds LOUD, easy to load. For this price you cant beat this!

The weight is similar to my real-life Glock17 9mm pistol. I don't know what the complaints about it being too light are for.

Seriously this is a fun BB pistol to shoot, don't think twice, just pick one up! Buy some extra mags and Pellgunoil too.

3. its light and and when you hold it....well its just perfect. If you want a bb gun thats going to make you happy this is it. I've done my research and this is the one that i chose.
