Pearce Grips’ Glock Magazine Extension enhances the capacity and ergonomics of any Glock mid- or full-size full metal lined magazine.

Designed to replace the original floor plate and internal locking plate of a full metal lined Glock magazine, this extension increases the capacity of a 9mm, .40 S&W, or .357 Sig magazine by two rounds and a 45GAP magazine by one round. Made of high impact polymer, the magazine extension can withstand drop tests at temperatures ranging from -20° F to 350° F.
