They made a pretty good single-action revolver (styled like the Colt SAA) back in the '60s and '70s, in the usual chamberings, .357/.38 Spl. .45 Colt, and maybe .44 magnum, I can't remember exactly.
They were very well made, but somewhat different in feel than the Colts, dimensional differences and all that. They sold fairly well at first, but sales tapered off after awhile, when Colt got the SAA back into production for a time.
