I think I must be due for a new carry belt. My current one is an MTac Kydex reinforced belt that has always been great, and is still great for mid-size or smaller guns. But, if I try to carry OWB with a full size gun, I have to wear it very tightly to keep the gun from moving around a bit. Tight enough that I end the day with a back ache. Or, maybe I need to switch to a lighter full size gun than my 48+ oz loaded railed 1911. I could trim about 10 ounces from the gun by switching to a Glock 21 (and add 5 rounds too), but I shoot the 1911 better.
