Pearce Grip Frame Insert for Glock Gen4/Gen5 Mid & Full Size, Black Polymer

The Pearce Grip Frame Insert (Pearce Grips part no. PG-G4MF) is a black polymer insert built for Glock Gen4 and Gen5 mid- and full-size frames, including the 17, 18, 19, 22, 23, 24, 31, 32, 34, 35, 37, 38, 44, and 45. Pearce Grips shapes it to drop into the open cavity at the bottom rear of the frame using a simple friction fit, no drilling or gunsmithing required. It closes off a gap that otherwise collects lint and range debris, while leaving your factory interchangeable backstraps fully usable. Whether you’re running a duty, competition, or carry build on any of the covered models, this insert gives the grip a cleaner, finished feel.
