As the name indicates, the M&P 380 Shield EZ is chambered in .380 ACP, one of the most popular personal-defense cartridges on the market. But unlike most .380s, the Smith & Wesson isn’t a sub-compact pistol. It comes with a larger grip than most of its competitors, which allows it to hold eight rounds in the magazine. That added size, along with a 3.675-inch barrel, makes the M&P 380 Shield EZ much more accurate and manageable to shoot than really small .380s. The added barrel length wrings more velocity and energy from defensive .380 loads than most shorter-barreled guns. And even though it’s larger than most competing .380s, the M&P 380 Shield EZ is smaller and lighter than many single-stack, striker-fired 9mm carry guns.
