I really like .357 Magnums, they're extremely reliable and practical. It's only going to fire when you really mean to pull the trigger, none of that misfiring nonsense. I'm not going to be carrying a rifle when some hoodrats try to rob me, but chances are once I'm 21 I will have one of these bad boys. I'm a big fan of the double action as well.
I've shot a shit load of guns. But I have shot a AR15, 30 ought 8, 30 ought 6, 12g, 20g, .22 Rifle, .38 revolver S&W, .9mm S&W and Beretta, .40 Sig, and some more I can't remember.
