The ProMag DRM-A126 is a 50-round drum for the Smith & Wesson M&P Shield chambered in .40 S&W. It turns the compact Shield into a high-volume range gun, so long strings and drills run without stopping to swap magazines.
The housing is molded from an impact-resistant DuPont Zytel-based polymer, with over-molded steel feed lips for a rigid fit and consistent feed geometry. A precision injection-molded follower rides on a heat-treated stainless steel spring for smooth feeding, and the drum is made in the USA with a matte finish.
