I have two old model flattop .357 Blackhawks. One is a 1958 vintage 4 5/8", and the other is a 1960 vintage 6 1/2". Both are in great condition, and both shoot great.
I wanted to convert them to .44 Special, but I ended up getting a new model .44 Special flattop so I can just leave my old models as is.
I'd be a better listener if you stopped talking about stupid crap that doesn't matter.
