These are simply perfect. Easy to install, perfect match with the O-rings. I have been procrastinating a few years to install these on my Ed Brown, and I'm sorry I didn't put 'em on sooner. They have solved the grip screw/bushing loosening problem and provide a very solid "feel." I've had a couple email conversations with Mr. Challis, and can say his products and customer service are first class. If I had more 1911's, I'd put the Hex Drive Bushings and O-rings on every dang one!

I bought this set of bushings for my Les Baer TRS. This is the 2nd set of Challis bushings that I’ve purchased.

Both sets of bushings are perfect, no fitting required. I have used other brands of standard bushings but they all required some fitting for clearance so the magazines didn’t drag.

Buy with confidence.

No matter how carful I am, I usually mess up the standard grip bushings upon removal. Not anymore! Also, when I added the bushing and grip screw o-rings, I no longer have a loose grip.

Very pleased with these products.

Not only did they fit as promised, but the hex design allowed them to be installed without any marring. It looks very professional. I’m very happy. Donny

Excellent !!!!

They are all I use
