I'm surprised that the P239 stayed on the shelf that long! Used ones are few and far between around here, and usually sell within a few days. I can only guess about the New Hampshire stamping, it must have been one of the early models. Neither of mine have that on them, just the West Germany thingy. In my opinion, one of the best carry pistols ever made, the perfect size. So far, four people who've looked mine over have since bought their own, and one of them was a die hard Glock fan!
