Availability: In Stock
The Promag Glock 48 9mm blue steel magazine is a reliable, domestically-made backup or primary mag for Glock 48 shooters who want solid steel construction at a practical price point. Built from heat-treated high-carbon steel with a black oxide finish, this magazine combines traditional manufacturing—stamping and welding—with modern precision molding for the follower and spring components. Whether you're training regularly, carrying, or just want a few extra mags in rotation, a steel-bodied 9mm Glock magazine from a US maker holds up to hard use.
ProMag has built a reputation on no-nonsense magazines that work. The steel body resists cracking and fatigue better than some polymer alternatives, and the heat-treated chrome-silicon spring is engineered to maintain reliable feeding and seating over thousands of rounds. The injection-molded follower keeps rounds properly aligned and feeding smoothly into your Glock 48.
Made in the USA and backed by a lifetime manufacturer's defect guarantee, this Glock 48 magazine removes guesswork from spare-mag shopping. Grab one or stack a few—you'll know exactly what you're getting: honest steel, proven design, and no corporate marketing fluff.
