Obviously, to each his own, but there is something I've noticed that may be worth pondering. I've seen a number of times that if someone can shoot a DA revolver, particularly a J-frame, really well, then he\she can usually shoot something like a Glock with aplomb. However, I've seen people who can run their Glock pistols like a boss act like they've never even seen a gun before if you hand them a J-Frame. Whether one chooses to carry it or not, I'm convinced that learning to shoot a J-Frame really well will improve most anyone's shooting with just about any self-defense firearm, carbines included.
