I have the very same Kel-Tec. Great for concealed carry in the back pocket or in my wife's purse. It's not a hand cannon, but it will get the job done. I really don't care if it kills the attacker or not; I just want the attack to cease.
When I first broke mine down, it was a beatch to separate and when I finally got it apart, the polymer frame cracked. I had to send it back to Kel-Tec for repair.
Luckily, it has a lifetime warranty!
