Smith & Wesson M&P .45 ACP 10rd Steel Magazine w/ Brown Base Plate

The Smith & Wesson M&P .45 ACP magazine is a factory-original 10-round detachable steel magazine purpose-built for the S&W M&P full-size line in .45 ACP. It pairs a blued steel body with a distinctive brown base plate, giving the mag a quick visual signature at the loading bench and the safe.

Engineered as a direct replacement for the original equipment magazine, this unit follows S&W's standard double-stack geometry and features clear-cut witness holes along the body for at-a-glance round-count checks. A corrosion-resistant finish shields the steel body from sweat and holster wear, while the steel wire spring delivers reliable feeding round after round.

Designed specifically for the Smith & Wesson M&P .45 ACP pistol, this detachable magazine is the correct factory fit whether you are replacing a lost mag, topping off a range bag, or running a full complement of factory S&W gear.
