I never owned a PF-9. I did have a Kel-Tec P-11. It was a neat little carry gun. I made a couple of minor changes to it that made it better for me. It did have a long heavy catchy trigger but once you learned the trigger it was accurate. I liked it okay but after a couple of years I got a different carry gun I lliked better. Sometime later a friend let me know he was interested in carrying a gun. I took him out to shoot with every handgun I owned to let him try them. He stunk with everything he touched until I handed him the little P-11. When I handed it to him he tore the center out of the target with it without even trying. It was a bit mind blowing as I had to work at it to become proficient with that little heavy triggered pistol. He offered to buy it on the spot. I didn't sell. A while later I just gave it to him for his birthday. It seemed like the thing to do & it wasn't worth much anyway.
