Yep, if you shoot hollow points in a P-32 you need to install what's called a " Fly Wire" in the magazine to prevent "rimlock".
tzimm007; Could be a few reasons. First, I'd make sure your P-32 is clean. Because of the small size they can be prone to malfuntion if one gets overly dirty. If clean, take and run the tip of your finger over the feeding ramp at the breech of the barrel feeling for any burrs. Lightly buffing it with emery cloth might solve your problem. If that fails, I'd try a differant magazine. Also, make sure you are not "limp wristing" when shooting it. If all that fails, send it back to Kel Tec. Besides repairing it you'll get it back with any and all upgrades plus they'll usualy do a full "Fluff & Buff" on it. Best service department anywhere!
