I wont carry anywhere other then in pocket and I wear Levi 505s so there's little room for anything large. For me ideal is very small and light, like a derringer or low cal mousegun. I don't wear loose or bagy clothing and my skin is very sensitive so I can't have anything metal against it. I literally can't carry anywhere but pocket and have a gun concealed.
Now, when I open carry, I do so on belt and drop leg and as large as I've got, because I'm doing so in the woods where bobcats and mountainlion and bears can cross my path. I've usually got at least two guns on me in these situations, upwards of five. Some are just for plinking fun if I find a spot or a squirrel looks at me sideways and I hafta bust a cap in his arse, and the belt and dropleg are for protection against something large and nasty that doesn't just keep walking.
