Challis Grips 1911 Hex Drive Grip Bushing O-Ring

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 du Mfg: Challis Grips
