This unit replaces the magazine floor plate to add approximately 1/2 inch of gripping surface for better comfort and control without sacrificing concealability. It blends with the contours and texture of the handgun and has a factory appearance. The grip extension is made from high impact polymer and withstands drop tests in a range of -20 F to 350 F. This unit fits Taurus PT-111/Kel-Tec P-11. It does not alter magazine capacity.
