The target grips on my Highway Patrolman shift out of alignment slightly, particularly when the gun is fired. I have to squeeze the grips to pop them back into place. This is apparently because the hole on one side of the grips was chipped putting the on the gun. I tried shifting the rod that goes through the frame to put it deeper into the hole, but that doesn't seem to work

Is there a solution to fixing these grips? What about filling the hole with epoxy and recutting the hole?

Filling the hole and redrilling it would probably work as long as you can drill a new hole that’s the right size and correctly aligned. I don’t know how this would work but I would be tempted the coat the area with a heavy lub like Vaseline to protect the metal then use very little epoxy in the hole and put the grip in place for the epoxy to form around the pin.

Someone will probably be along with a more professional way of doing it.

That's what I was thinking, or plastic wood mite work.

I have never had an issue with grips coming off. Filling & re-drilling makes sense, but you would have to be precise. You could make an insert of rigid tubing or other to put over the pin to better fit the hole. I have never done it, but would work. Grips not altered, gun not altered. Bob

I also like the idea of filling & re-drilling the hole. To get the new hole in the right place, I would remove the stock alignment pin, hold the repaired stock panel in the exact position, and mark the stock panel through the hole in the frame.

To get a good mark, I would use a drill bit that just fits through the pin hole but hold it in your hand or in a small hand-held chuck to get the hole started . . . or your can go ahead and finish drilling the hole by hand using the pin hole as an alignment guide.

Good luck,

Slather Vaseline or oil on the pin and frame.Put a bit of epoxy in the hole of the grip.Install the grips and align them while keeping the damaged grip on the bottom and let the glue dry for a few hours.

fill the hole with super glue, epoxy can separate from the wood, super glue will take wood with it if it comes to that. You may not even need to completely fill the hole, reducing the diameter may solve your problem.

Both Russ and John are right on track. The only trick is to make sure you align the panel correctly or the new hole will be in the wrong place. Also I would use gel super glue and stuff a little wood dust in on top of the super glue, Let it harden, sand flush and then drill your hole. Good luck.

If it's only off diameter by 5 or 10 thousandths of an inch, I would try to put a slice of veneer in the hole. That would be less permanent to start with and would not require any drilling. When you get the right placement and the right thickness you can put a dab of yellow glue on the veneer to hold it in place using a drill shank or perhaps an appropriately sized finishing nail.

I have done this many times fitting grips to single actions with good results using JB Weld. For a release agent I apply a lite coat of any old gun oil to pin and frame areas that may come into contact with the JB Weld.
