As I have said before, Kel-Tec is just not given much respect around here (literally and figuratively). I took my PF-9 to my local range after getting it Dura-coated and listened to my buddy, a retired Air Force pilot and crazy 'Nam Vet, give me hell for relying on it as a carry pistol. UNRELIABLE!!, he shouted. Cheap and unreliable....
I loaded all 4 mags with Speer Gold Dots, my carry round, and beckoned him onto the line to show me how unreliable it was. He burned through them as fast as he could, then, clutching his well wrenched wrist, went to wash up. I went through another 50 rounds of Win. white box target ammo without problems. Point made.
Spend more if you must. After all, it KICKS with full power loads, but you will carry it when others may be too large or too heavy. The trigger reset is long, unlike most 9mms, and takes a little getting used to, but it is not a deal breaker in my opinion.
Let us know what you end up with and how you like it.
