Trying to figure that out...
I really like the Del Fatti PH-3 platform because it always keeps my firearms (Seecamps) upright in my pockets. However, they are hard to find for the R9
I have also had success with the Hedley Merlin for my Seecamp, so I just ordered one to fit an R9.
I have come to realize that I need pocket holsters that have a wing on them. With that being said, I may end up selling my Meco front pocket holster too. I love the quality, but it flops over in my pockets (to the heavier slide side) and I find myself checking and readjusting it too often.
