Story goes like this: someone modified this back when 1911s were a dime a dozen to be a bullseye gun. 1.7 million serial number puts the frame at 1944 for Remington Rand. Slide is marked Remington Rand. Everything is blued (is that correct?). The front of the grip has been stippled, the slide has been drilled for a pic rail, and the trigger has been modified. Otherwise it's a pretty regular 1911 from what I can see. Anyone recognize this pic rail? Says RRA on it, can't find it on the internet. I'd like to remove it and put irons back on. Anything else I should know? If my goal was to get a WWII era shooter for plinking with non-nuclear loads, did I win?
