I found a US GI Colt 1911 made in 1944, marked Property of USA and I think it had US Army on it too. The gun had been refinished in a bright blue and was sporting target sights which makes me think maybe the slide had been replaced. It was also wearing faux pearl or ivory grips. The guy said he would sell it to me for $1000 otd. I was just wondering if the alterations that were made to it would hurt the value seriously. I know those things go for several thousand dollars. So if you are knowledgible about these guns please give me some guidance.
