Hogue Fancy Hardwood grips are some of the finest grips available. They are precision inletted on modern computerized machinery, then hand finished on actual factory frames to assure proper fit. Grips are constructed of the highest quality, kiln-dried hardwood available. Each grip is unique and will vary in color and figure.This grip uses a pin through the grip to secure the grip to the frame. To change the grip, the pin must be driven out. Replace with the pin included with the grip. Please review the instructions included with your grip. If your frame pin is 1/2" across or less, you do not need to change it out for the included pin.
