I'm forcing myself to eat some cabbage , onions and polish sausage. Seasoned with onion powder , garlic powder , and Mrs. Dash. I'll get it chocked down I'm sure.
I believe you are getting two different revolvers mixed up. The Single-Six is normally a .22 rimfire. The .357 is the Blackhawk. Both are very fine firearms.
What length barrel does it have? $600.00 is a good price for what you describe.
