For IWB I use the FIST Rounded Front Clip holster in Hybrid(ultra thin kydex under leather). Works very well. Also use a Kramer IWB #3. Very good stuff but adds to the bulkiness of the gun. For a belt holster, I was using a FIST Easy On in Hybrid(thin kydex under leather). Both Fist holsters have very good retention and very slick draw. Of late, I've been using a Safariland 3-slot pancake and a Blackhawk Detachable Slide holster. The Safariland is bomb proof. Once you get it on your belt, it stays put. The Balckhawk is just very convenient to put on and take off. I also use a Bear Claw paddle holster now and then. Bear Claw is out of business now. Hope this helps.
