To me being accurate to the original also means,,,,drum roll,,,,Materials!
To find a 1911 that is made using the same processes and materials, now that is a real problem, is that Colt straight up that way? I really don't know, it would really make me feel good to think that anyone, for any price, is making one the way they should be. No MIM, no plastics, no cast, personally I wouldn't care about CNC, that just means the same methods done to perfection part after part, but a true purist might.
Steels? Does anyone make steel parts with the same amounts of carbon even as the originals? This I really doubt.
I haven't seen a case hardened grip screw since I sold a WW2 1911 A1 I had, but that's how they used to be made. How about the finish? That deep blue Colt used to use. The magazines were "In the white" for the last third at the top, because the bluing process effected the heat treating of the feed lips.
Is that Colt pretty close in all these areas? If so I'd like one myself, it would be like going back in time 100 years. Many of our modern methods are greatly superior, and many are a shame for American manufacturing, and I feel like I'm the only guy saying that out loud. Colt is as bad as almost any of them in giving the American consumer what he doesn't know is compromised materials and processes, maybe we'll see a change in the trend.
