It works well. I think I am going to get a few more sets.

The Challis hex bushings make the days of ruined bushings because of broken screwdriver slots a thing of the past. I wish I would have known about these earlier than I did. Excellent idea!

These are so much better than factory bushings. O-rings are also great and make the fit much tighter and secure.

This is the second set I have purchased/used to replace standard slotted bushings. I damaged the original slotted bushings I was taking off and have since purchased a Challis bushing removal tool to facilitate the removal of future slotted bushings. Challis products are pure quality and I highly recommend them.

I recently found a grip screw loose on one of my pistols. Investigation revealed a stripped grip screw bushing. I had heard great things about the Challis hex drive bushings, so I look a look at the website. I found the oversize repair bushings and the related tap, so I purchased those, along with a bushing removal tool and some bushing "O" rings.



The repair went perfectly, and I loved the way the bushing worked with the "O" ring. So I purchased some standard bushings and "O" rings for the grip screws too. Now the grips on that pistol are rock solid! I will be purchasing more Challis bushings for all my other pistols too!!
