S&W M&P Shield Plus

Overview

The Smith & Wesson M&P Shield Plus is a polymer-frame, striker-fired, micro-compact semi-automatic pistol chambered in 9mm Luger. Introduced in 2021, it evolves the long-running, slim single-stack M&P Shield into a higher-capacity micro-compact by adopting a stacked (tapered double-stack) magazine, raising flush-fit capacity to 10+1 and extended capacity to 13+1 while keeping nearly the same slim, concealable profile. Designed for concealed carry and everyday carry, the Shield Plus also brought a noticeably improved flat-face trigger and S&W's first M&P bladed trigger safety, with optics-ready and manual-safety configurations available.

History & Background

Smith & Wesson released the M&P Shield Plus in 2021 (reviewed by American Rifleman in April 2021) as a major update to the original M&P Shield, which had been one of the best-selling concealed-carry pistols in the United States since its 2012 debut. The "Plus" designation reflects the jump in capacity made possible by a redesigned tapered magazine that fits more rounds into a grip only marginally wider than the single-stack Shield. The launch responded directly to the wave of high-capacity micro-compacts such as the SIG P365 and Springfield Hellcat. Smith & Wesson subsequently expanded the line with optics-ready models and Performance Center versions featuring ported barrels and fiber-optic sights.

Design & Features

The Shield Plus keeps the slim, rounded, snag-free silhouette that made the Shield popular, but improves capacity, trigger feel, and grip ergonomics.

• Action: Striker-fired, semi-automatic
• Capacity: 10+1 with the flush-fit magazine and 13+1 with the extended magazine; two magazines (one of each) are typically included. The tapered magazine design adds capacity with only about a 0.15-inch increase in grip width over the single-stack Shield.
• Trigger: A flat-face trigger with a lighter, crisper pull and a tactile, audible reset. It is the first M&P pistol to use a bladed (hinged) trigger safety.
• Grip: An 18-degree grip angle (consistent with the M&P family) and an aggressive, multi-zone stippled texture for a secure hold.
• Slide: Stainless-steel slide with an Armornite corrosion-resistant finish and front and rear cocking serrations. Optics-ready (OR) versions are milled to accept a micro red dot.
• Sights: White three-dot sights on standard models; Performance Center models add fiber-optic sights. Optics-ready models are cut for a red dot.
• Safety: Bladed trigger safety standard; a low-profile left-side manual thumb safety is offered on thumb-safety configurations.

Intended Use

The M&P Shield Plus is designed first and foremost for concealed carry and everyday carry as a primary defensive pistol, and its slim profile also suits backup-gun and deep-concealment roles. The improved trigger, higher capacity, and optics-ready options make it equally well suited to regular range training and personal defense.
