The Smith & Wesson M&P (Military and Police) is a polymer-framed, short recoil operated, locked breech semi-automatic pistol introduced in the summer of 2005 by the American company Smith & Wesson. It uses a Browning-type locking system. While targeted at law enforcement agencies, the M&P is also widely available on the commercial market.
The M&P is a hybrid evolution of the Smith & Wesson Sigma and Smith & Wesson SW99 design but does not share parts compatibility with the Sigma. The M&P design has an improved trigger and enhanced ergonomics that allow for end-user customization. An industry standard Picatinny rail and a higher grip has been afforded with an improved grip and beavertail. Many of the ergonomic study elements that had been incorporated into the Sigma and the Smith & Wesson SW99 were brought over to the M&P. The improved trigger weight and feel and the unique takedown method (not requiring a dry-fire pull of the trigger) were meant to set the M&P apart from the popular Glock pistols.
The M&P is a striker-fired semi-automatic pistol. This trigger system prevents the firearm from discharging unless the trigger is fully depressed, even if the pistol is dropped. An internal lock and/or magazine disconnect are available as options and an optional external thumb safety became available in 2009.
The pistol frame is made out of Zytel polymer reinforced with a stainless steel chassis. The pistol comes with three removable and interchangeable grips. The slide and barrel are made of stainless steel, that after hardening is treated with a proprietary nitriding process called Melonite. The Melonite process produces a matte gray non-glare surface with a 68 Rockwell C surface hardness rating. The pistol has a low slide profile which holds the barrel axis close to the shooter's hand and makes the M&P more comfortable to shoot by reducing muzzle rise and allowing faster aim recovery in rapid shooting sequence. The slide has four contact points with the frame. This was done to make the rail system self cleaning, by leaving room for any dirt or small foreign objects to fall out of the weapon.
As the slide of the pistol enters battery, the striker engages the sear. At this point, the sear is held back in a partially cocked condition. When the trigger of the M&P is pulled, the trigger bar first engages the firing pin safety plunger, lifting it upward, and releasing firing pin safety. At the rearward extreme of the trigger bar's travel, it engages the sear. The sear is rotated downward by the trigger bar, fully cocking, then releasing the striker. The striker makes contact with the primer of the chambered round, which in turn ignites the gunpowder and propels the bullet forward. According to M&P gunsmith Dan Burwell, the angle on the rear face of the sear creates a camming action against the striker. This camming action moves the striker to the rear very slightly during the trigger pull, thus finishing the "cocking". This system is similar to the partially tensioned striker found in the Glock series of pistols. When the pistol cycles for the next shot, the striker will be automatically pre-set in a 98% cocked position. Because the striker is only 98% cocked prior to the trigger being pulled, Smith & Wesson classifies the M&P's action as "striker fired (double action only)".
The M&P factory trigger is of the jointed type and has a trigger travel of 7.6 mm (0.3 in) and is rated at 29 N (6.5 lbf). The M&P45c models have a slightly higher rated trigger pull of 31 N (7.0 lbf). The competition oriented M&P40 Pro Series have a reduced trigger pull of 20 N (4.5 lbf) due to the installation of a Smith & Wesson performance center sear. Massachusetts (MA) approved models have a trigger pull of 45 N (10 lbf). The pistols are delivered with two magazines.
The standard iron sights are of the three dot type and made of steel. Both the front and rear sights are dove-tailed into the slide, and can be horizontally drifted to adjust for windage correction. An integrated Picatinny rail can be found underneath the slide on the front of the frame for attaching tactical lights, lasers and other accessories.
There are ten-round magazine versions of each pistol available for the California, Massachusetts, New York, Australian, and Canadian markets. Novak tritium night sights are an available option for both the full-sized and compact versions. Another optional accessory is the stainless steel lanyard pin. The new pin replaces the original solid plastic pin with one that has a stainless steel ring embedded for use with a lanyard.
The M&P9 JG is a standard size Champion series variant named for Julie Golob and fitted with a Warren Tactical rear sight and a fiber optic front sight. Besides the three standard black grip inserts it comes with two small and medium-sized pink grip inserts. A portion of the proceeds from sale of these models will go to a breast cancer awareness charity and an awareness ribbon is etched on the slide of the pistol.
In 2008, Smith & Wesson introduced new versions of the M&P: the M&P45 Mid-size, the M&P45 Compact, the M&P9L, and the M&P Pro Series. The M&P45 Mid-size sports a 102 mm (4 in) barrel and a full-sized grip, and the M&P45 Compact targets the concealed carry market with its 4" barrel and shorter grip (with eight or ten-round capacity).
In 2011, Smith & Wesson released the M&P22, a cosmetically similar handgun chambered in .22 Long Rifle. The internal construction and blowback operation of this rimfire cartridge variant is the same as the Walther P22, which Smith & Wesson used to import into the United States, and completely differs from the center fire M&P variants. Rather than the three-dot sights found on other models, the M&P22 has a single dot on the front sight and notch rear that is adjustable for elevation and windage. In 2013 the scaled-down M&P22 Compact was released.
In 2012, Smith & Wesson introduced the M&P Shield in 9mm and .40 S&W. The Shield is a subcompact single-stack magazine variant of the M&P line. The Shield has roughly the same silhouette as the M&P Compact but is considerably thinner at less than 1-inch in width. The Shield is the first M&P to incorporate an improved trigger with positive reset. In 2016 a .45 ACP variant Shield was added to Smith and Wesson's product line. The .45 ACP Shield variant has a 0.2" longer barrel (measuring 3.3") and exhibits larger overall dimensions.
In 2014, Smith & Wesson introduced the M&P Bodyguard 380 in .380 ACP. The M&P Bodyguard is functionally identical to the previous released Bodyguard 380, which it replaces. The M&P-branded Bodyguard removes the integrated laser sight of the previous pistol and brings the aesthetics in line with the rest of the M&P product line. Unlike the rest of the M&P pistols, the M&P Bodyguard is not striker-fired. It is a more traditional double-action-only hammer-fired pistol intended for personal protection, concealed carry or as a law enforcement "back-up" gun.
In 2017, Smith & Wesson introduced the M&P 2.0 series. Changes include a full-length steel chassis, a rough textured grip, and the improved trigger system of the Pro series.
