I am very happy w/ the Blackhawk non-Serpa holster.

They do not specify the 2.0 pistol though so I'd call and ask. It's inexpensive and comes w/ both a paddle and belt loop attachment. I find that I like to use the paddle as a belt loop. I put the belt through the spaces but the entire holster stays outside my pants.
