Pro Mag Industries Magazine for Glock 28 Features This ProMag magazine is purpose-built for the Glock 28 in .380 ACP offering a 25-round capacity for shooters who want more rounds on hand between reloads than the factory magazine provides. The magazine body is molded from a proprietary DuPont Zytel based polymer an engineering-grade material chosen for its impact resistance and long-term durability. Inside a full length steel insert is stamped and welded much like the factory magazine construction reinforcing the feed lips and body against repeated loading and firing cycles. This blend of polymer body and steel reinforcement keeps the magazine both light and long-lasting. Feeding reliability comes from an injection molded magazine follower that tracks smoothly through the body as rounds are stripped and chambered. The spring is made from heat treated chrome silicon wire chosen for its resistance to fatigue across thousands of loading and unloading cycles. Finished in black polymer the magazine matches the factory look of the Glock 28 while providing a useful capacity boost. Manufactured in the USA this ProMag magazine is a solid choice for shooters who want a dependable spare or extended magazine for their Glock 28.
