Here is my take on the sillyness of this whole thing.
First, I think it is hilarious that some person decided that the BOLT is where the final comparison separates ways. If they would open their eyes they would clearly see that USFA SAA's are of a wholesome beauty that we could only dream about until USFA came along since no one has made the fit and feel with the kind of American quality that was witnessed in the 1st gen. Colts.
Second, if Colt was concerned about improving on the age old deisign of the SAA, they would have more than likely made the same type of improvements that todays manufacturers have made. Example, beefed up cylinder, better metallurgy on springs, and todays machinery with more consistent tolerances for just a few. Remember, Bill Ruger not only knew the SAA had a market demand, but he also knew it needed some improvements.
Third, how do we know that proposed USFA Bolt in the picture wasn't an early USFA Bolt that was made by Uberti. I know for a fact that all of the parts are now manufactured here in the USA, but to get off the ground USFA did have parts made by Uberti and then custom assembled and finished them here, much like the Second gen. Black Powder Colts. Anybody can go to the factory and ask Gary for a tour.
Finally, the real beauty of the SAA is after the machining, it is in its hand craftsmanship that makes each gun a custom fitted firearm. To trim metal in the right places for that custom fit, there needs to be metal there to begin with.
As far as I am concerned, USFA SAA's are not Colt Clones. USFA SAA's are custom American made Single Action Firearms with the kind of quality our Grandfathers grew up with, and they blow anything in its Class away, including the Colt itself.
I am entitled to that opinion, and I will exercise my right to display my opinion by buying USFA SAA's, lots of them!
