It was a match 1911 that I bought off of one of my Staff NCOs back in the late 80s. He was stationed in Quantico a few years before I met him and one of the armorers built a gun for him as a gift. The only commercial parts used was an Essex frame, a Bar-Sto barrel, and high-mounted Bo-Mars. Everything else was spare GI parts that was available at the armory. Paid $250 for it and it came with one of those wooden shooting boxes with the scope mount. The thing was a tack driver and had an absolutely beautiful trigger. As the training NCO for my unit, I even took it to the field during live fire training exercises. It "looked" GI enough that my Gunny and OIC looked the other way and let me get away with it.
I really wish I held onto that gun as I learned a lot tinkering with it. By the time I sold it in '94 to help pay for college, I had "upgraded" the pistol with Low-mounted Bo-Mars, which did require milling the slide, Wilson Commander hammer, Wilson match sear, extended thumb safety, full length guide rod, and a drop-in Wilson beaver tail safety. You know that saying "You don't realize what you have until it's gone."? So true.
