I would normally agree with you on that, however, I was lucky enough to get an ASM that was lovingly refinished by the person I bought it from....Works great....But Uberti stills sets the standard, but they (1847 Uberti`s, and several revolvers that I would like to get), are difficult to come by....I have a pair, 1 Uberti and 1 Armi San Marco, the Uberti is twice the gun when compared to the ASM. You just can't compare the fit and finish between the 2 of them.
Try VTI parts...They have everything you need in parts replacement, conversions, and they ship to Canada...I`ve never had a problem.....I've seen cartrdge conversions for these (in magazines), anybody know if they are available here?
