Hi, all. I just put a Colt MKIV oacp on layaway at my local gunshop (actually, my wife did...it's a gift). Anyway, I'm not as familiar with Colts as I hope to become, but I was wondering about the production run, what was the start year and end year? Also, the finish is matte blue curves, polished blue flats. It's gorgeous, but not a finish I've seen. Has it been refinished or is this something that was offered by Colt? I can't wait to bring her home, it's my second 1911, but my first Colt. Thanks for your help. I've had a hard time nailing down officer-specific info. But lurking here for a while, I know you guys know your stuff.
