Probably more like 10-25% depending on what I am wearing. I prefer to carry a small or medium semiauto IWB if I can, but my 642 carries great in a pocket when I can't.
I pocket carried a Colt Cobra for several years before moving to an LC9.
I debated about getting an Airweight j-frame so I could lighten the load but still carry a revolver. I opted instead for something that allowed me to carry an extra magazine. The inability to find a good solution for carrying .38 reloads was one of the major factors that made me want to go with a semi auto.
