As always, a good holster on a stiff belt can go a long, long way. Kydex all day, every day. It won't absorb sweat, it is thinner than just about every other material, stiff enough to provide safe reholstering and a close ride. Bladetech Phantoms are ~$30, and are probably the best deal in the bidness.
Just my opinion obviously but holsters were meant to be made out of leather not plastic.
