About a year ago I picked up a Colt 1911A1 38 Super made in 1955. It was "customized" - aftermarket trigger, hammer, sights, grips, MSH, barrel, grip safety and bushing. Luckily, the "bones" and finish were still original. I have since replaced all the aftermarket parts except the barrel w/ original parts and she looks great. My dilemma is whoever did the customizing drilled a 1/16" hole in the left side of the frame for a set screw which held the grip safety in the "on" position. The hole just bugs me as it's ugly even though it doesn't affect the funstion. I've been debating the best way to fill this hole. Should I have a smith weld a plug in, grind it smooth and re-blue that part of the frame? How about lock-titing a plug instead and re-bluing the plug only? Or leave as is and live with it? I'd love to hear the thoughts of some of the experts on this forum. TIA.
