Unfortunately, I got into guns after USFA was already gone. There are probably many models or versions that I have never seen but of the ones I have seen I like the Ainsworth the best. A nearly exact replica of the first SAA's Colt made and they can be shot with black powder or smokeless.Did USFA ever make a Frontier Six Shooter with the etched panel? If so, that would be just as cool as an Ainsworth.
