Aluminum frame grip bushing repair?

[K Frame Keith]

This is a general gunsmithing question I hope fits here. I have a Kimber CDP that has a lot of rounds through it. I have stripped out one grip screw bushing from the aluminum frame. I've actually done it twice thru the years and have already exhausted the oversized bushing option.
Question is: what options do I have now? Is the frame repairable or do I have to return it to the factory? Thanks in advance for your suggestions.

Maybe a rivet nut? Hieli coil? Maybe a Tig weld and redrill?

Many years ago I fixed an alloy frame Colt Commander with stripped bushing threads by simply using epoxy to hold the bushing in place. It seemed to work OK.

There are two Loc-Tite products that should work. The first is "Sleeve Mount". This is the high strength green used for installing auto engine cylinder liners and valve guides. These are hi temperature, dynamically loaded applications. The Sleeve Mount should work. This is available from just about any automotive store. Be sure to buy the "Clean and Prime" also, this is the catalyst for the Sleeve Mount. Follow the instructions implicitly!

The second is, I believe, called "Black Magic". This is a gunsmithing product used for mounting shotgun ribs, revolver ejector tubes on heavy recoiling revolvers, and similar. This is available from Brownells.

To avoid problems in the future be careful about over tightening the grip screws. If the screw bottoms out on the end of the bushing it will jam and pull the bushing when you try to remove the screw! You may have to replace the stock panels if they have been damaged by over tightening the screws!

Been there........Done that.......It worked.

Thanks everyone for your assistance. I'll start my research tonight and will update when the repair is a success. Thanks again.

I found a LGS who said he could TIG weld the frame then drill and tap the frame for a new bushing. He did suggest trying epoxy as a low cost alternative. I figured there was nothing to lose. I cleaned up the damaged threads, applied a metal compatible epoxy and just for good measure, used a staking tool to expand the bushing slightly. Tight a a rock. Thanks everyone for your advice.

You can re tap and install an oversize bushing.Kimber s are great for not applying thread locker to the bushing threads . I make grips and hate installing them on Kimbers for that reason
Sorry did not read the OP Use a #60 "o" ring on the screws to keep them from binding on the bushing that way you won"t torque them to the bushing
