Beautifully designed and machined! This grip bushing system is fabulous. All 1911 manufacturers should use this as OEM !

These are the best products on the market. Stainless steel hex head bushings should be required on all alloy frame pistols. I have them on all my 1911's. the hex head screws and o'rings are icing on the cake. Very quick shipping and a great product. Excellent.

These O rings are the real deal. They made the slim grips on my 1911 45 fit so snugly. Virtually no play before setting the grip screws. Definitely a must have, if you're changing the bushings out on your frame.

Used the Challis bushings on my Colt 1911. No longer any fears of screwdriver slippage as with th more conventional bushings. A low cost insurance policy to aid in avoiding damage. A highly recommended upgrade for your 1911!

These bushings are a much better design than the traditional slotted bushings. They can be installed or removed with a 7/32 inch hex wrench unlike the traditional bushings which often require a special tool and are very easily damaged. The Challis bushings also come in a shorter size for slim grips. Switching to Challis bushings was a night and day improvement and a no brainer for me.
