Challis Hex Drive 1911 Grip Bushing O-Rings secure grips and prevent damage, especially to delicate materials, by absorbing impact and reducing movement during recoil.
Designed for periodic replacement, these O-rings ensure a firm hold by expanding against the grip's counterbore when the grip screw is tightened.
They protect the frame from abrasive grip materials like G10 and prevent bushing loosening from heavy materials, enhancing the longevity of both grips and bushings.
