Smith & Wesson M&P 5.7 – 5.7x28mm with Thumb Safety

Smith & Wesson M&P 5.7 — 5.7×28mm (With Thumb Safety)

High capacity, high velocity — modern M&P performance with an extra layer of manual control.

The Smith & Wesson M&P 5.7 is a full-size, high-capacity pistol chambered in 5.7×28mm that blends a novel Tempo® rotating barrel system with an ergonomic M&P polymer grip package. The thumb-safety model adds a user-controlled manual safety for shooters who prefer explicit mechanical retention while carrying or storing the pistol. Contentstack+1

Why It Stands Out

The M&P 5.7 brings a fresh take to the M&P family by pairing one of the fastest commercially available handgun cartridges with Smith & Wesson’s Tempo® barrel engineering for enhanced repeatability — and then packages it with very high magazine capacity for its size. Adding a thumb safety gives shooters who want manual mechanical control an option without sacrificing the platform’s modern features. Contentstack+1
