Smith & Wesson M&P 15-Round Magazine 40 S&W Steel Blued

The Smith & Wesson M&P 15-round magazine delivers reliable feeding and consistent performance for 40 S&W pistols. This factory magazine features steel construction with a blued finish and brown polymer floor plate for enhanced durability and corrosion resistance.

What Makes This Different

Factory Smith & Wesson magazines undergo rigorous quality control testing that aftermarket alternatives often skip. The steel body construction provides superior strength compared to polymer magazines, while the precision-formed feed lips ensure consistent cartridge presentation. The brown polymer floor plate offers impact resistance and easy identification among mixed magazine collections.
