I carry my Sig P229 in .40 S&W in a Crossbreed Super Tuck Deluxe horsehide IWB holster, 2 spare mags in a Blackhawk polymer double mag carrier all held up by a horshide with internal polymer stiffener from The Beltman. Love the setup, it's very comfortable and durable. I bought them in horsehide because of the extra stiffness and the resistance to moisture over bullhide. I also have a Blackhawk CQB level 2 retention OWB mostly for open carry.
