Being an ex NYPD living in Florida, I have carried magasafe in my pony pocketlite, seecamp 32, P9 compact, keltec 32, and the R9, and haver never had a problem with this ammo......For the R9 I contacted Tony at "magsafe" and he advised me to use the mini glock round in the R9 and the recoil is less then their "defender" rounds. I have had no problems, but,,,,,,,,,Lately with all the problems getting posted with the R9's I am thinking of switching to my Pony Pocketlite when it gets shipped back from a complete meltdown and customizing, from " showgun" in South Florida, pictures will follow when I get it back. Never like to worry about the gun I am carrying!!!! Geminidan
