These KCI USA's Glock pattern magazines are constructed with a hardened steel insert that is encased in a polymer. The polymer molding helps to protect the magazine body from damage and deformation from regular use.

The KCI® 9mm 10-Round Magazine for Glock® 17 Pistols is a popular aftermarket pistol magazine among budget-conscious and personal defense shooters across the country. It has a durable, high-impact polymer body with a hardened steel lining for long-lasting performance and factory-like field performance you can count on. Numbered witness holes provide quick, at-a-glance round counts, improving reliability when on the move. Furthermore, the robust steel spring and anti-tilt polymer follower work together to ensure accurate cartridge alignment and jam-free feeding in any setting.

If that isn't enough, this magazine features precision-molded, steel-reinforced feed lips for a secure, wobble-free fit and increased functionality in high-stress situations.
