What Lobo said.
I also have a Don Hume JIT Slide. For me it is okay, but not great. The pancake gives more support, and keeps the L-Comp in closer to my body. It also provides a little more protection for the gun. I tend to bump in to things in my job.
I have an old Bianchi ballistic nylon holster with snaps for belt loops. Dang thing was cheap as heck, but has a thumb break, is very lightweight, and was really cheap. This one goes to the range, and works very well with the L-Comp. It's just ugly as sin, and has about as much sex appeal as a used Yugo.
