Now since I have owned 4 of the Kel-Tec's in the past......trial & error and I am guilty ok! Nonetheless, the P-11 has a mile Looooooong trigger pull and is not as easy to hide as the P-9 or PF-9. I finally got a more reliable pistol in this last Kel-Tec PF-9, it will shoot hollow points the others would not.
The pistol is very accurate for a cheap pocket pistol. I have shot 2.5 inch groups at 21ft using rest and Blazer FMJ ammo. However, those Kel-Tec's will JAM if you "limp-wrist" them. You must also let that trigger come all the way forward, inorder to keep from Jamming on the next shot........this takes practice but in the heat of excitement (being car jacked) one could forget and not let that trigger come all the way forward and then your goose would be over cooked or brunt. I only use this pistol around our place in the hot summer months wearing shorts. Now on the street or in my vehicle, I'll bet my life on my Glock or Sig-!!!
