I usually conceal carry a P-01 or a PCR most of the year IWB or OWB; except in the very hot humid summers of the St. Louis area where the humidity can reach 90% and not a rain cloud in the sky. You can break a sweat just going out to get the mail. In summer I carry a Sig P938 in a Talon wallet holster in the cargo pocket, and it works great. It looks like I am carrying my wallet in my left thigh pocket.
I just bought a Rami BD recently, and I can shoot much tighter and farther groups with it than my P938. I can carry my RAMI BD in all of my cargo pants & shorts with a universal pocket holster. It is noticeably heavier and does print slightly. A "Pocket Grabber" for RAMI BD does fit my cargo pockets. I think I just might order one anyway; it not all that expensive. I love all of my other High Noon holsters and belts they work great.
Just like to have another option for carry in the hot humid summers of St. Louis. IWB is not an option the heavy sweat ruins holsters(2) and pistols(1).
