Went to the shop today to see what they had and there was a P-3at, black/blued there that was purchased and never fired for $199.99, sold! So now i've got the PF-9 and the P-3at, great carry combo. Carry the PF-9 by itself, the P-3at for deep concealment, or the pair! Also looked at an SU-16 they had used as well. Also had a sub2000 that would match my glock 9mm mags.... Hi, my name is Mike and i'm a Kel Tec addict... What is the way to tell the difference between the 1st and 2nd generations??
