KCI USA 50rd .40 S&W Drum Magazine for Glock

This KCI USA drum magazine provides a high-capacity magazine option for firearms using the Glock magazine pattern in .40 S&W. The body is molded from glass-filled polymer with a clear portion that permits visual round count inspection; hardened steel inserts and robust internal components support feeding. A load-assist lever is included to ease loading; due to the weight of a fully loaded drum, the magazine is not designed to be drop-free when loaded. The manufacturer notes the lifetime warranty is void if the magazine is disassembled and indicates it is not designed for use with hollow-point ammunition.
