Pearce Grip GRIP FRAME INSERT, MODEL 20/21 SHORT PG-FI20SF

Plastic plug installs in the bottom rear cavity of the frame to fill the opening found in Glock® pistols. Front “lip” forms a tight, flush bond with the mag well to help make sure the mag goes where it should, smoothly. Keeps dirt and debris from finding its way inside the pistol and gives a clean, smooth look. Uses the lanyard hole for retention to snap firmly into place.
