Would like advce regarding my recent purchase. I picked up a 1956 Colt Commercial frame with a complete GI Remington Rand top end mounted. Someone installed a drift-adjustable rear hi-vis sigt with a center witness mark on the slide. It has a higher blade front sight as well. Most likely done by a military smith. Should I attempt to get a GI frame or attempt to find a commercial slide setup. i am interested in a relaible, accurate shooter which I can gradually add upgraded components.
