I'm in the market for a revolver. I've always like them. .357 is my caliber choice. My question has to do with barrel length. I'm stuck on a 4 inch barrel. I'm just not a fan of snubbies. Carrying is not an issue. I'm just wondering is there much of a difference in the 4 inch barrel and the 6 inch barrel? I wouldn't carry this daily, just now and then. Any help will be appreciative.
