I have a few S&W and a GP100 revolver but I picked up Single Six about a month ago. It has a 5 1/2 inch barrel in blue with wood grips and the extra magnum cylinder. So far I've put 400 rounds of various brand ammo with no problems at all. I like it so much I'm thinking about a Blackhawk maybe as a Christmas present to myself. I have a couple of 357 revolvers so I'm thinking about a 44mag or even a 45 convertible. Any advise?
