Challis Hex Drive 1911 Grip Bushing O-Rings are an integral part of what makes Challis’s hex grip bushing system on of the most secure methods for installing 1911 grips. They help you maintain a firmer hold on the pistol and prevent damage to grips made of delicate material. Since they absorb impact, the O-rings do wear out eventually and should be replaced periodically for best effectiveness.

As you tighten the grip screw, the O-ring is forced down a conical seat and outward against the counterbore in the bottom of the grip. When the grip is fully seated, the compressed O-ring holds the grip firmly in place, isolates it from the bushing, and prevents it from shifting around during recoil.


For maximum protection, use in conjunction with Challis grip screw O-rings (sold separately)

Long-wearing synthetic rubber construction

Available in 8- and 24-packs


Challis Hex Drive 1911 Grip Bushing O-Rings will reduce scuffing of the frame by grips made of abrasive material like G10 fiberglass composite, and they protect expensive fragile grips such as bone, legally-harvested ivory, and mammoth tooth. They also minimize loosening of bushings caused by heavy grip materials like carbon fiber, aluminum, titanium, and G10.
