Shield Arms S15ME5INSG3BLK S15 Magazine Gen 3 15rd w/ +5rd Mag Extension (20rd Total) For Glock 43X/48 Black Nitride Steel

Description

This is a Shield Arms 15-round 9mm magazine for the 48, in Black.

This is a full-size standard-capacity magazine, the usual choice for duty and range use. Magazines are consumable: springs and followers wear before the body does, so buying spares and rotating them is cheaper than chasing feed problems later.

Several states and cities cap magazine capacity, and those limits change. Check your state and local rules before ordering – we ship to your address or your dealer, but we cannot ship a magazine somewhere it is not legal. Magazines ship directly to you with no FFL transfer.

The S15 magazine is a patent-pending, flush-fitting 15 round magazine for the Glock 43X and Glock 48. The S15 is a steel magazine, and is the same length as the OEM Glock 10 round magazine, but holds an additional 5 rounds. What changed with the gen 3 magazine? We made the following improvements: US-based manufacturer. Modular tooling. Raised ribs on the back of the magazine allows these to fully match the OEM magazine position in the mag well, which should eliminate any tolerance stacking that results from Glock frame variations. New steel, new coating, new heat treat process – new steel is slightly thicker, tougher, and now comes with a new standard black nitrocarburized QPQ finish for a high degree of corrosion resistance
