One great thing about being a "gun" guy is that I don't have to stick with just one choice so I change my carry guns from time to time.
Right now I am back on a Glock kick so when I carry an auto, I carry my G19 IWB with one spare magazine slipped into my back pocket next to my wallet.
In revolvers, my current favorites are my S&W 642 fitted with a Houge Monogrip and my out of the box 638. The 642 is the one that I carry most often. It rides IWB and I carry a speedloader in my right front pocket.
The 638 is my pocket gun in a Uncle Mike's pocket holster, usually in my right front pocket, but if it is serving as a BUG it gets switched to the left side
Other items that I carry are a little keychain sized can of pepper spray, cell phone in a clip on holder, cheap S&W folder clipped into my right side back pocket, keys and wallet.
