Does anyone out there have a tap for the frame threads of a 1911 grip screw bushing? My Sistema Colt's got an issue -- I don't know if it was someone's staking job gone wrong or what, but one of the grip screw bushings was loose and turned out to be stripped (external threads on the bushing, not the frame). It was getting looser and looser and making the gun less fun to shoot.
No problem, right? Get another bushing, install, done. I picked up a few at the last Indy 1500 gun show and after our most recent trip to the range, had a try at swapping out the bad one, which was when I discovered it was essentially de-threaded.
The problem: there's a burr or something on the tapped hole in the frame, which very neatly eats up the threads of the bushing. The threads are too fine to clear with an X-acto blade (sneaky trick but sometimes it works on shallow tapped holes). So, I need a tap. $39.99 new at Brownells, ouch. 'Druther buy a used one, or borrow one (on pain of replacement if damaged, taps being what you might consider an occasionally consumable item).
