Pearce Grips’ Glock Gen 4/5 Magazine Extension enhances the capacity and ergonomics of your Glock 26, 27, 33, or 39 subcompact pistol’s magazine.

This magazine extension replaces the magazine base plate and internal floor plate while blending with the contours and fourth generation texture of the pistol to provide a factory appearance. The extension increases the capacity of the Glock 26 magazine by two rounds, the Glock 27 or 33 magazine by one round, and the Glock 39 magazine by zero rounds.

Made from high impact polymer, the magazine extension can withstand drop tests at temperatures ranging from -20° F to 350° F. Increasing the magazine’s grip surface by 5/8”, the extension provides better control and comfort without sacrificing concealability.
