I have a Liberty SAA clone in 45 LC one problem I bought it and stuck it in the safe and forgot it, when I finally got around to shooting it maybe five or better years later I know I know
I found out that after six rounds or so it would lock up. I checked the cylinder to forcing cone clearance and could just barely get a .002 feeler gage in there, using a sheet of glass and some 320 wet & dry sand paper and a figure 8 motion I opened that to .005. Plus a member told me to double check all the screws tight, found two loose and so far it seems okay.
I shoot light cowboy loads in it using Trail Boss. I think its really a Pietta knock off.
