Description

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.

Shoot either steel BBs or lead pellets through this CO2 gun.
  • Smith & Wesson M&P 45
  • CO2-powered
  • Semiauto
  • 8-shot rotary pellet clip & 8-shot rotary BB clip
  • Shoots pellets or steel BBs
  • Double- and single-action*
  • Fixed front sight
  • Rear sight adjustable for windage
  • Integral accessory rail
  • Synthetic frame
  • Textured grip
  • Manual safety

*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.

Everything. I wish Umarex would make more pistol replicas that utilize that reliable 8 shot clip. Solid polymer slide/frame, metal internals, metal 'slide' release/safety/trigger. Not quite a tack driver at 10 yards but pretty close, for the price I've got zero complaints.

I would have liked a co2 mag like the Umarex cp99, that would let me toss a grip sleeve on.

Do yourself a favor and pick up a cheap rear sight red dot plate and a red dot sight. You can go as cheap as you feel, it doesn't need to hold up to any recoil. I use the UTG RDM20 plate and a Pinty dot. Remove the grub screw on the rear sight, it slides out, slide the plate in and you're ready to go.

Accurate representation of the M&P 45. Able to use UTG RDM20 mounting plate to put a red dot on the thing. Trigger is actually pretty good, with two distinct stages, the first where it's rotating the cylinder with the pellets, and a very crisp second stage break when it fires. As with any CO2 powered gun, the power does drop off pretty fast, especially when firing rapidly, but I am able to get around 96 shots off and maintain 8 shot, 1" to 1.5" groups at 25ft with cheap Crosman 7.4grn pellets before things start spreading out more.

Better CO2 cartridge loading system.

As I am putting red dot sights on many of my firearms these days, I bought this as a pellet pistol to mount a cheap one and get more practice in. First setup was just sticking a Pinty pistol red dot on the flat top with double stick tape, but I found that the UTG mounting plate that is made for the firearm version which also works with the Pinty as it is setup like a Vortex for mounting.

I like that this gun has a similar trigger pull as my little .380 bodyguard. I like that it has the capability of using pellets and bb's. It is very accurate. It is a very fun and affordable way to practice.

It looks like the price of an additional mag for it is very expensive in comparison to the price of the gun.

This is my second gun. If I had not contacted pyramid air when the first one had an issue, my review would have been much different. From the start, the first one had a very hard trigger. I thought that's how it should be. Then it got harder, and eventually wouldn't shoot unless you cocked it first. They gladly replaced it. The 2nd one is a total joy! Keep in mind, it should have a very long trigger pull, but shouldn't be too hard. If it does, you may have gotten a faulty one. Before giving the gun a bad review, contact pyramid air. They are wonderful to work with.

Information that anyone needs before ordering this gun. We've had two more since the first review. It was impossible to seat the cartridge. Umarex said we would not be able to use Crosman or Daisy cartridges. Crosman is all that is available locally. All it would take for this gun to work perfectly would be slightly longer bolt to tighten on the cartridge. We broke one and replaced it with a thumb screw that works like a charm. The other one has been returned.

This is a close replica of the real fire arm. The single action and double action are nice features and the eighty or so shots per co2 cylinder are useful. The removable rear sight allowed for the installation of a dovetail red dot mount and sight. Also appreciate the picatinny rail for inclusion of a laser sight as illustrated in the included photo. Reasonably accurate with wadcutter ammo out to 30 feet. Though not a target pistol, it's good on soda cans and knock down targets.

For the price of this one, I can't fault it, it's a fun shooter that gives a sufficient number of shots and hits the target 95 percent of the time. It's also customizable.

Spent about $100 for the red dot mount and sight and this included the green rechargeable laser also. The pistol shoots well with open sights if you're not inclined to upgrading. You can also pick up a S&W M&P carry case for less than $25 to complete the set.

Perfect for my needs to get a micro red dot onto a pellet gun for practice. Given that it's now a blowback and has a flat top, was able to mount a cheap optic to it with double stick tape. Total cost of the gun and optic is actually under what I would spend in ammo these days on a typical range day.

Wish it had the CO2 loading system of the Umarex M1911 A1. The double action trigger is a little on the heavy side but at least its consistent.

Never bothered shooting it with the iron sights.

very well made. Most accurate of this type, 5/8 inch group, 50 shots at 20 feet. Gets 100 shots per cylinder. Great 3 lb trigger. I will order another one. Very happy with this gun.

Became impossible to open the action after 200 shots. Simple solution to the problem was to bevel the locking lugs that allows better opening. removing the barrel screw and front slide gave easy access to the locking lugs .Magazine causes cocking to be a little hard as the magazine rotates into position while cocking the single action feature. Magazine sprockets need to be a little more pronounced. The gun breaks in after a while and becomes easier to cock. no further adjustments made this a perfect gun.

Get one or two.

Format is like the real thing. Accurate. Fun to shoot!

Trigger pull distance and force... but definitely not a deal killer.

Great cost point. Quick delivery, even during the holidays!
