My favorite pocket holster, front or back, comes from Stoner Holster. Very reasonable, he stands behind his work and mine has lasted for three years working every day without a fail. Definitely worth a look.
poets58 if you haven't already bought one check out Bear Creek holsters. I bought a pocket holster for my Kel Tec PF-9 and love it. I carry it in cargo pants and sometime in a jacket or vest. It's a great little holster. Doug who I spoke with walked me through the process since I was clueless on what to expect or buy. He didn't just sell me a holster he made sure I knew what I was getting and probably would have to change my dress to accommodate the holster (aka cargo pants) to carry the Kel Tec since it's a little on the large size for pocket carry but with cargo pants with large pockets it's great. He even made me a nice IWB magazine holder. Well hope you find the right holster
