Hey guys, my LGS has a new 617 4" bbl that I will be looking at tomorrow and hoping to purchase. Please explain the "canted" barrel issue to me and what to look for. Also please explain tool marks and any other thing that I need to look for. I'm very excited about getting a 617 and and after hearing all the bad things about S&W quality control I want to make sure that I'm getting a good one. Thanks in advance for explaining this "canting" issue for me.
