JD, I have one of Mark DeCoveny's (MarkTHG here on TFL) YCS holsters for my Champion. The holster's too long, by an inch because he uses a gov't size holster for is, but so far, no probs at all. It's a strong side IWB that doesn't close up when you draw. chose against having a thumb strap, and I'm glad I did. I can shake the holster upside down and the gun won't fall out (I wouldn't keep on doing it, but it really holds fine), but a quick tug on the gun releases it from the holster. A good belt is also a must and Mark sells them too. I've found that with this setup, I can carry my Champion all day and no one's the wiser.
