.357 SIG chambering has been discontinued. 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 2007 the full-size
.45 ACP version of the M&P was introduced sporting a barrel. This model also won
Handgun of the Year in 2007. 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 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 centerfire 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 longer barrel, measuring in at top length of , and exhibits larger overall dimensions. In April 2021, the original 1.0 Shield platform was discontinued after the release of M&P Shield Plus. 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 M2.0 series. Changes include a full-length steel chassis, a rough textured grip, and the improved trigger system of the Pro series. In 2018, Smith & Wesson introduced the M&P 380 Shield EZ. As the name suggests, the Shield EZ has a number of convenience features including an easy-to-rack slide and an easy-to-load magazine. In late 2019, Smith & Wesson added a 9mm offering to the Shield EZ line. Both the .380 and 9mm variants feature an internal hammer. In spring 2021, Smith & Wesson introduced the M&P Shield Plus in 9mm. An evolution of the M&P Shield, the M&P Shield Plus, among other improvements, utilizes a double-stack magazine to increase capacity at the sacrifice of a slight increase in width. In November 2021, Smith & Wesson introduced the M&P M2.0 chambered in
10mm Auto to the M&P M2.0 family. Smith & Wesson offers a barrel compact model and a larger barrel model. Both models with have a 15-round magazine capacity and are built on the M&P45 M2.0 frame. The M&P M2.0 10mm Auto features a new M2.0 flat face trigger and comes with an optics ready slide from the factory. An unloaded 15-round 10 mm Auto magazine weighs . In January 2023, it was announced that a
5.7x28mm variant, the
M&P 5.7, will be released with a new gas-operated, locked-breech, rotating threaded Tempo Barrel System and a 22-round magazine. In July 2023, it was announced that a
.22 WMR variant, the
M&P 22 Magnum, will be released with a new gas-operated, locked-breech, rotating threaded Tempo Barrel System and a 30-round magazine. In July 2025, Smith & Wesson announced the introduction of the
M&P22X. It comes with 20-round magazines & was designed to be a competitor to the
