Pearce Grip's Grip Extension replaces the magazine base plate, but retains all other factory components. It does not alter the capacity of the magazine and provides better comfort and control by adding approximately 5/8" of gripping surface. 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.
