What holster do you use and do you find any problems edc this pistol?

I do occasionally carry my 9mm 320 full size. I have three holsters for it:
Safariland ALS. R&R Holsters Kydex Belt Slide. Muddy River Tactical Kydex Paddle Holster. The R&R holster conceals fine for me. To me, as a long time full size 1911 carrier, the carry experience is not much different than that with the 1911.
