I know I am in the minority here, but I still use a DeSantis superfly nearly all the time. I love the look of nice leather and have holsters from several of the top makers that are talked about here, but the DeSantis seems to work the best for me and is gentle on the pistol's finish.
The holster stays upright for me all day, the gun draws easily without having to hook the holster on my pocket to remove it, and for me it is very comfortable. Easy on the finish also. I use them for the R9. PM9, Solo, and now a Boberg.
