That's what it appears to be. Is there anywhere I can get the slide authenticated? If it's from WWI or WWII I wouldn't want to shoot it much but if it's a later make I'd like to take it to the range.Better pics would help. Have you tried to look the SN up? It might be that what you have is original hardware that's been restored. Could be a later 1911 from Colt with an older slide to give it a USGI appearance.
Seriously if it is sound, shoot it enjoy it and think about the stories it could tell.That's what it appears to be. Is there anywhere I can get the slide authenticated? If it's from WWI or WWII I wouldn't want to shoot it much but if it's a later make I'd like to take it to the range.
