I know it's not practical in very many situations, but if the weather is cold and I'm wearing a heavy coat and not likely to be taking it off, ( fair, rodeo, etc., ) I have been known to carry my Desert Eagle .50AE .
With two extra mags to boot!
It's not right for every day, but if I get the chance I do like to carry it. It's not that heavy to me any more, after a job I had working out of a remote drilling camp in Alaska for four summers. Up there it was just part of getting dressed every day. I was never without it 24 hours a day. By the way, I did shoot a bear with it too. ( among other assorted unfortunate "wrong place, wrong time" critters. ) It worked rather well.
So I know if I have to use it, if I hit'em, they're goin' down! HARD! Any way, that's the biggest I've carried.
