I love carrying my R9 in this light weight Kydex paddle holster.
I'm so happy I connected here on the forum some time ago to this guy Dave that built it for me.
Here it is pictured on the right, on the left is a kydex pocket holster.
It sits tight to my body, retains the R9 real well, has plenty of room for me to grip when I need to draw. It is comfortable.
