Smith & Wesson M&P .45ACP Handgun Review

Regular readers of this publication will know that we are fans of the venerable .45 ACP cartridge. John Browning’s genius back in 1904 still packs a solid punch and all the newcomers to the dance haven’t improved things very much. Because of this affinity for the .45, I’m always looking for another piece to add to my arsenal in this caliber. This brings us to this month’s review: the Smith & Wesson M&P .45.

First some background: the M&P (Military and Police) is a short recoiled, locked breech semi-automatic pistol manufactured with a Zytel reinforced polymer frame and the slide is Melonite coated stainless steel. The first M&Ps were introduced by S&W in the summer of 2005 with the .45 caliber full size production in 2007, followed by the mid, compact and Pro series in 2008. S&W offers a dizzying array of models when it comes to their .45 M&P. You can have this pistol with or without a thumb safety (required for military trials), in full-size, mid-size or compact, with either the 4.5 or 4 inch barrel and in states that require a magazine disconnect safety (more on this later) with or without that option also. Oh, and you can have any of these in black or Dark Earth Brown frame.

Smith & Wesson M&P Handgun both sides

Although shown here in .40S&W, the controls and overall "feel" are the same no matter which caliber it is.

The pistol has a striker-fired mechanism similar to that of a Glock or Springfield XD. It is closer to the XD than the Glock as the Glock has a tensioned striker. Anyone familiar with either of these pistols will have no problem disassembling their M&P. One change of note; there is a sear deactivation lever that “allows” the user to separate the upper assembly from the lower (field strip) without having to pull the trigger. For someone used to stripping a Glock, this is a mild annoyance. You will need some device (a pen will do) to pull the lever up to disengage the sear, allowing the slide to ride forward. There is also a loaded chamber indicator in the form of a viewing port on top of the slide.

Smith & Wesson M&P handgun controls

Starting top center and working clockwise: take down lever, slide stop, trigger safety, magazine release.

What I noticed first about this pistol was how comfortable it was, right out of the box. This was due to the interchangeable (there are three) grips or palm swells that ship with each pistol. When I initially handled this in my local gun store (LGS), the medium grips were installed. Having tried all three at home I settled on the small, thinking it would make the transition to slide and magazine release easier. Well, it did, but it didn’t fill my hand as well as the medium while shooting. Since shooting is the whole point, I went back to the medium grips. They are very similar in feel to my .308 bolt stock’s grip. The M&P series also come with ambidextrous slide release and a magazine release that can be installed left or right. I tried it on the right side… too different from my other pistols. Those of you who only carry one firearm and have small hands might like it. Maybe not.

The sights that come installed are standard three dot and are dovetailed into the slide, front and rear. There is an integrated Picatinny rail in case you want to hang some bling off the front of your pistol. The M&Ps ship with two magazines but I was lucky enough to have a coupon from Smith & Wesson for two more magazines (woohooo!). The .45 caliber mags are stainless steel and a bit more expensive than other calibers.

Now, since I live in the socialist state of California with all her idiotic gun laws (you people in Massachusetts will understand), this pistol came with a magazine disconnect “feature.” What this means is there is another lever inside the magazine well of the lower receiver, right next to the sear deactivation lever. Having done a bit of research (Google is good), I found that you can remove this lever and install a small spring to take up the space. It turns out that a 1911 magazine release spring, cut down to length, works perfectly. Now I can have a functioning weapon without having to have the magazine installed. Duh.

After a couple trips to the range with this pistol I came to the conclusion that the trigger pull was a bit notchy for my tastes and I was having a hard time determining the reset point of the trigger. With a little research I found the people at Apex Tactical Specialties had just what I was looking for. I ordered up a Hard Sear and the Ultimate Striker Block. Apex also offers the Mag Safety Deactivation Spring for $4.00. Anyone capable of pulling their pistols down to pins should have no problem installing these items. That being said, you should have them installed by a gunsmith if you have ANY doubts about your ability. One thing I noticed that put me off was the use of rolled rather than solid pins in the M&Ps. I’m not a big fan of rolled pins. I’m sure someone can come up with a good reason for them (other than they’re cost effective) but I can’t think of one.

So, back to the range I went with the Hard Sear and Ultimate Striker Block installed and a few more magazines. My group size did reduce noticeably. I’m pretty comfortable saying the trigger improvement was most of the reason. Of course, some of it was just getting more time behind the pistol. After firing over 1100 rounds of everything from crappy ball reloads to full power duty loads, I did not have one malfunction. One shooter at the range complained that the spent cases were bouncing off her forehead but after watching her shoot I determined that her grip needed help. She was essentially limp-wristing the pistol. After correcting the issue the brass was thrown directly right, as it should. I had no problems hitting a one-foot diameter steel plate at 25 yards with this firearm. It balances well and the pistol sits pretty low in my hand, helping get my follow-ups back on target quickly.

My first thought upon receiving the M&P was to use it for practical shooting competitions. Maybe pair it up with an AR and a Benelli M4 and try some three-gun competitions. About the only thing I can think of changing on this pistol is the sights and get a few holsters. I’ll probably go with some XS-Sights and a Blackhawk! Serpa in a waist setup and a MOLLE carrier for a tactical vest. As for now, I’m just going to shoot the crap out of this .45 and get as comfortable with it as I can. I may have found my new favorite handgun.

    Our sheriff purchased these. Another deputy and I experienced misfeeds 20% of the time. Way too much for a combat weapon. I went back to my Glock. The M&P makes a great paper weight!

    It’s strange how people have completely different experiences with the same weapons. I was a Sheriff for 9 years and for the last 5, we were issued Glock 22s/.40 cal.I had zero issues of any kind with the Glock and in Canada Glock is pretty much the go to service weapon for almost all departments who carry sidearms. Of course,the RCMP had to be different [read cheap] and carry the old 5906 in 9mm.
    I have owned and shot pretty much every handgun available and nearly every time I had a semi-auto that was cranky, the problem was the magazines. Kimbers are notoriously fussy about mags and have very tight chambers but they’re high quality pieces.
    I now have an M&P.45 and my gun dealer says he has had no M&Ps returned in five years. Not something that would indicate any reliability issues. I like the M&P,it’s simple and well designed.
    When I’ve put a few hundred rounds through it, I’ll post the results.

    I have owned Smith weapons my entire life and to date I have never experienced a single malfuntion with my 915, MP9, MP9c and now MP45, I shoot a couple hundred rounds a month an one or 2 IDPA matches, but all I shoot is factory loaded ammo.

    I’ve now put well over 2,000 rounds through my M&P .45. I’ve got 10 magazines (all S&W) and haven’t had a single problem. Did one day of 500 + rounds without cleaning, no malfunctions. Other than the modifications listed above the gun is stock.

    I’m not saying this will replace my 1911s or even make me give up my Glocks. but I would have no problem trusting my life to this weapon.

    If you buy junk ammo for almost any weapon you will have malfunctions. It’s like putting piss in a car a gas tank and hoping it will run. I’m curious to know what exactly the first poster was talking about when he said this was “way too much for a combat weapon”. I’m not a police officer, and not quite sure what dictates combat on the civilian side of the fence. But I’ve served two tours in Afghanistan as an Airborne Infantryman, and I’d gladly take this weapon into combat over the wore out Beretta 9mms the Army issues.

    My departmen was getting brand new M+P.45s in the boxes…straight from the factory and some of the sights were falling off and in others the insides of the barrels were already rusty. Between that and the severe misfiring problems we are now going to Glock 22/23s depending on officer assignment.

    I own a M&P40 and love it. all i have been shooting with is reloaded ammo and yet no malfunctions whatsoever! I, however, thinking about doing the trigger job. I believe with the trigger job, this M&P will beat the glock all the way. I actually rent the M&P9 and glock 17 (9mm) at the range, and i like the M&P9 more due to its recoil, ergonomic, and accuracy.

    I’m looking into .45 cal. and seriously condering the M&P45. I tried it at the range and loved it!!! Also, you can get 14 rounds mags for it online too. My second choice is either the CZ 97B or Sig p220.

    Just a quick update: This M&P .45 now has well over 5,000 rounds through it and I like it better every time I shoot it. I have to admit that I haven’t been all that diligent about her cleaning and she doesn’t seem to mind at all. Accuracy is better than I’ll ever be and I’m even considering purchasing a smaller version (perhaps 9MM) for carry.

    I did have the opportunity to shoot a stock version without the modifications (article above) and I’d say everything I’ve done was money well spent.

    Looking forward to seeing how she’ll shoot at 10,000 rounds. Better start reloading…

    FNP Tactical .45 is the best 45 out there…

    I have a Smith and Wesson 45cal semo Auto that after loading the clip and attempting to cock and place a round in the chamber, it is so stiff and hard to slide it back that I can’t hardly do the action. What is wrong or is I am just too weak or is the spring to strong?

    Have had an M&P for over a year now and returned it to the factory because POA did not come close to POI. It shot way low. Well, it still shoots low after being returned from the factory. I’ve kept it and shot it with different loads hoping to find one that will shoot to POA….no luck. I’m going to contact S&W and return it telling them if it doesn’t shoot to POA don’t bother returning it. On another note: this gun shines in every other category, no problems with FTE or FTF, indeed I’ve had no failures with different ammo and I’ve shot enough rounds that my trigger has actually improved. No longer the 8lb gritty piece it was when first purchased. Don’t know what lb it breaks now but it’s no more than 5lb. IN SHORT: I love the gun but can’t have it hitting as low as it is, it’s a deal breaker if Smith can’t fix it.
