I was in one of my regular pawn shops today. They had a 18-3 with a fair amount of bluing wear. This 651 and the blued version which I will assume is a 51. I'm sure I have heard of these before but I don't remember it. A J frame square butt 22 mag. The price was fairly high I thought, but the guy dropped it $100 when I asked if he could come down. I'm not an impulse buyer, but I was today. I paid $800 for it. I hope I did OK. It is pretty clean. I can't wait to try it out tomorrow.
