I just got finished working with Crossbreed Holsters Superslide OWB holster, Instructor Belt, and their OWB dual mag pouch. Crossbreed uses Kydex for the holster shell and leather or horsehide for the backing plate. It can be worn strongside or crossdraw. A great, high quality product and company. Watch for the full review in an upcoming digital issue of Tactical Gear Mag, along with a review of the Auto Ordnance M1 Carbine-a timeless design that still has a lot of fight left in it.
