I just picked up a ruger sp101 with a 2" barrel. I love the gun. Anyway, after looking up some simple ballistics info, it appears that a good .357 mag load really shines out of a longer barrel. The short barrel doesn't allow the round to meet its full potential. It appears that 124gr +p gold dots are more effective out of my glock 26. Any insight would be appreciated. Wanna kill these ads?
