I've just ordered two holsters from Active Pro Gear. One is their model 29 crossdraw. Its an IWB holster that I'm going to try with my R9, if it works well enough I'll either continue using it, or have one similar made of leather.
http://www.activeprogear.com/crossdraw-loop.htmlThe other I ordered for a different pistol is what they call their Modified Small of the Back holster. This is from their site, "A regular Small of the Back (SOB) holster places your gun over the base of the spine. A fall or hard blow with your gun in that position could cause serious spinal cord injury. Our holster is engineered for kidney carry to avoid that danger."
http://www.activeprogear.com/15-sob.htmlThese both are nylon type holsters. I figure they're cheap enough that if they don't work, I'm not out all that much. I do have from them, their DeepConcealment Shoulder Holster, which so long as I have on an undershirt, I find to be very comfortable.
So here are some more choices, just to make your task a little more difficult, (you're welcome).
