ASM = Armi San Marco. Depends on who you talk to as to what they think of 'em. I've seen some excellent guns by them and then I've seen some that left a lot to be desired - but, on the by the same token, I've seen and handled some Uberti and Pietta that I could say the same about. I own two ASM - an 1862 Colt Pocket Police and an 1861 Colt Navy - both are great pistols - high quality, fantastic fit and finish and good shooters. The only thing I've heard on the negative side is that the internal parts can sometimes be softer than other brands - but - I'd still buy another one if I ran across a model I wanted at a price I was willing to pay and the quality was good. I think Doc Hoy has one or two as well and you might pm him and see what he has to say. I think he's worked on them and can probably be a better source of info on the internal parts, etc. I think the availabilty of parts is also and issue but I've heard that Deer Creek has some parts for ASM. I'm sure that there are others on here that have experience with ASM as well. Good luck and safe shooting!
