My personal belief is that the ultimate carry revolver is the one you're most likely to have with you. Your 442 is pretty much perfect in my opinion. I've known guys who claim to carry larger pistols but they never seem to have it on them because they're not wearing the right jacket or something. That's not to say that those who recommend them don't carry them but it's a whole lot more pistol than many want to lug around in a truly concealed arrangement. I own a beautiful 2.5" K frame that I love to shoot but if I wanted to make it my carry I know that half the time it wouldn't be with me. My M&P340 only holds 5 rounds but, I always have it with me. If I'm going someplace where I figure 5 rounds of .357 won't suffice then I really have to question why I'm going there in the first place.
