Sig Sauer P320 P250 9mm Luger Blued Steel Extended Magazine

The Sig Sauer MAGMODF921 extended magazine delivers reliable 21-round capacity for P320 and P250 pistols chambered in 9mm Luger, combining Sig Sauer build quality with practical features for range sessions, competition, or duty use. Constructed with blued steel for durable, corrosion-resistant service life and finished in a low-glare black, this magazine fits Sig P250/P320 platforms precisely and feeds smoothly thanks to a robust, low-profile follower and spring tuned for consistent chambering of 9mm Luger rounds. The extended base increases capacity without significantly altering grip ergonomics when used with compatible pistol models, offering more rounds between reloads for training drills, match stages, or extended shooting sessions, while the magazine's dimensions and feed-lip geometry maintain reliable lockup and ejection cycles. Listed under handgun magazines and pistol magazines, the MAG-MOD-F-9-21 part number identifies this accessory for shooters seeking a high-capacity, metal-construction option from Sig Sauer that integrates into common 9mm workflows and enhances readiness on the range or in competition.
