COLT single action Army revolver, advice needed.

[Patronen]

There was a Single Action made by Beretta at one time. I am not sure if it is still listed by them? It might have been called a Stampede or something like that? I can't vouch for that model but Beretta has well, the Beretta name going for it and a lot of their products at least to me seem to be of good quality.
