I have been partial to a Blade-Tech IWB for the past 6 months. I also have a couple Kydex Belt holsters that I use under a sports coat, especially while out doing volunteer LE work. I carry a Glock 23 or 35 in them.
When in uniform, the LEA that I work reserve for mandates Accumold, so I use the Ranger model, with my Glock 23.
I have several Galco belt holsters, one of which I wear with my Caspian Meltdown.
I have an Ahern pocket holster and a high-ride Blade-Tech paddle for my Beretta Tomcat.
I also have a DeSantis Shoulder rig that I like very much for my Glock 23, especially when I know I'll be sitting a lot (including long drives).
