Outstanding quality and service. I would highly recommend Challis hex drive grip bushings.

Have purchased three sets of bushings, o rings for the bushing and o rings for the grip screws. Also purchased both size extractor tools. Products are top quality, perfectly machined and eliminate all headaches with 1911 bushings. And everything is reasonably priced and service is great! What's not to like???

After installing my Challis bushings I knew I had a superior approach to "gripping" my 1911. These bushings are very well manufactured; they display fine production of the threads as well as a nice finish. The Challis system would allow to very easily change from standard to thin grips and back whenever you desired.

First time trying these bushings, they are awesome no more stripping while trying to remove, I also got the o-rings with them and man are my grips solid now, will be installing on all my future 1911's.

Grip screw bushings are great, just long enough so they don’t protrude into the magazine well and combined with their screws make a nice combo. Using their bushing driver worked great.
