These bushings are easy to install and remove. Loctite is not necessary for installation if they are torqued to 18 in lbs for both steel and aluminum frames. Use 7/32" nut driver or socket.

These full size bushings will work with grips not less than 0.245" thick. Use our slim bushings for grips 0.185" to 0.245" thick. For still thinner grips use our extra slim bushings.

We strongly recommend using the the Challis bushing and grip screw O-rings because of the benefits they provide, such as preventing stripped threads, eliminating loose grip screws, scuffed frames and providing the most secure mounting available for the 1911. They may save your frame and you can feel the difference.

Tighter thread?

I tried to install the new full size grip studs to replace the slim grip Challis studs but the thread on the new studs seemed to be tighter and were harder to install. I decided to reinstall the old slim grip studs as they were easier to install.

Great hex bushings. I have these on every of my 1911’s
Why doesn't every gunmaker use these as original parts—they should!

These always make their way to my guns. With o-rings, never come loose during longish range sessions. Fitment is excellent.
