I lost one of the grip screw o-rings on my Kimber LW Arctic when upgrading to a nicer set. I found a 24 pack on the Challis website at a great price, they shipped the next day. Great company, great service, great product! I would highly recommend them to anyone.

These are good quality grip o-rings at a great price, fast shipping time and vvery reasonable shipping cost.

I use these on my Wilson with VZ grips. They do a fine job of keeping the grip screws tight. My only complaint is that due to their thin diameter, they eventually get chewed up after the the grips are removed multiple times. Not a big deal but I would recommend having spares on hand.

I have used the o-ring grip screw bushings in my two 1911 10MM which had previously shook the grip screws loose during each use. The grip screws did not loosen at all this time. I will see how they work over a longer period and would gladly rate them higher if they continue to perform so well. I have spare o-rings bushings to replace them as directed in the literature. Very good value.

I use these on all of my non-OEM grips to keep them nice and snug.

No more tightening grip screws after a range session, they stay tight.

These arrived a few days after I ordered them - excellent service!
