Most of us know the original 1911 prototype did not have a grip safety. That throws a bit of a wrinkle into the mix when trying to determine the "truest" copy as far as modern pistols go. If we are going to ask what is the truest modern made version of the 1911-A1 it is easier. I would say my Colt 1911-A1 is the closest (except that mine is stainless), but if we are going to say truest to the 1911 design I would have to say it just might be my Detonics pistols. If you set aside the funky sight placement and look at the gun from a functional standpoint you might agree with me...or you might not. What do you guys think.
