Wanted you make you aware of the Remora no-clip IWB holster. Bought one last week and it is pretty amazing. My normal carry holster is an Alabama High and Tight for my G36. I was looking for something to use when I was wearing sweats or shorts with no belt. You can place this thing inside your sweat pants, tighten up the draw string and make a quick trip to the store and it will stay put.
