I know what you're probably saying. You're probably saying, "Turk, what the hell is that?"
Yeah, you probably spotted it. Something not quite right about that top picture. It's actually a 1903 Colt that was converted to a 1911-pattern by Cylinder And Slide as a master project in gunsmithing a couple of years ago. Here's a link. Pretty amazing, huh? They call it the "Model of 2006."
And, yeah, the lower picture is "Before" and the upper one is "After." Wow.
[Correction: it is a .45-ACP 1911 that was modified to resemble a 1903 Colt. No less amazing.]
