I've had my PF 9 for about 6 to 8 months and I love it! I practice when I can and I clean it after each practice. I use Winchester 9mm Lugar 115 gr. ammo. But it has just started to jam on me. It seems it cannot eject the casing quick enough and sometimes the casing hangs up in the slide on the last shot and stuck in the ejection arm. USUALLY, if you rapid fire, they will all eject ok. But when it comes to slow fire, about every other one will jam. (Sometimes even in rapid fire, one will jam)I've cleaned it well and keep it lubricated well after each practice and I've even used other ammo. Same thing happens. Am I doing something wrong or is there a malfunction with my pistol. As you can probably tell, I'M not big into fire arms, but I am licensed to carry in the GREAT STATE of MISSOURI. Any help will be MUCH appreciated.
