Gun Belts by The Belt Man
Call them. They will tell you everything you need to know. I ordered a 1 1/4" black elephant skin w/7 holes and am very happy. I'm only 5'9", 200 but the 1 1/4" works fine for me and my smaller support needs (PM9, Ultra CDP II). In fact, after this post, I'm ordering another in shark skin. Again, tell them your needs and be prepared for excellent advice.
