I carry my pistol in a holster I made, modeled after this one here: http://www.rusmilitary.com/images/makarov_holster.jpg
I carry it on my belt either left or right side depending on whether I'm wearing a belt. It's not a very fast holster, but its still much faster then my pack, and it does a good job of protecting my weapon.
