Ruger Old Army Grip Frame Screws - thread and pitch?
Posted: Tue Mar 03, 2020 7:30 pm
Took the new (to me) Ruger Old Army to the range today. Shoots very well.
There's just one niggle - when I stripped it down for cleaning I discovered the previous owner had slightly stripped one of the two screws retaining the back of the grip frame (the ones either side of the hammer). I have some screws on order but I'd like to run a finishing tap through the affected thread just to tidy up any burrs that may be lurking there. As far as I can see the thread looks pretty good but if I gently screw the non-buggered screw in I can feel it tightening up a bit and I don't want to push my luck. It may just be some residual retainer down there - I gather the screws originally come with a blob of it on the threads. But like I say, I'd rather not push my luck when I can just run a tap through. Anyone know what tap I'll need?
