Description
ProMag Industries Magazine — .40 S&W, 15 Rounds (Fits S&W M&P-40) — Steel, Blued Finish
Reliable spare capacity. Factory-fit replacement for M&P-40 platforms.
This ProMag Industries 15-round magazine is a steel-bodied spare built to fit Smith & Wesson M&P-40 pistols. Finished in durable blued coating and assembled with a dependable spring and follower, it gives shooters an easy drop-in option for extra on-gun capacity during range sessions or as a serviceable replacement mag for training and daily use.

Why It Stands Out
A straightforward, affordable steel magazine that mirrors factory geometry for reliable lockup and feeding in M&P-40 pistols. The blued finish provides a classic look while the robust steel body resists deformation under heavy use—making it a durable choice for regular range work and spare-mag rotation.
