Welcome to the board! I'll bet the P-3AT is just the ticket for LA and I've visited Mobile/Fairhope during your sultry summers!
I've owned a P-3AT, P-32 and P-11. All three were fine handguns and the P-3AT was a favorite when I owned it. I purchased a S&W 642-2 which took its place as my pocket handgun of choice and felt the P-3AT was not needed anymore.
The nice thing about the P-3AT was its trigger pull and the fine accuracy it was capable of at relatively close distances. It was something its larger sibling the P-11 was incapable of and I would scratch my head and wonder why Kel Tec didn't put the same trigger in the 9mm.
I'd certainly buy a 2nd generation again if I felt the need to own one.
