I don't think that an airweight revolver and the P32 are in the same class. I would think that an airweight would be similar to a Kahr mk9 or even a Glock 26.
The Kel-tec P32 is in its own class. Lightweight, concealable and inexpensive. It is the most bang you can get in such a small package.
It is not a serious, fulltime CCW weapon. For that I wouldn't feel comfortable with less than 9mm or .38. However, if you are looking for something that you can carry all the time, in any dress, it can't be beat.
I have owned one for six months and it has worked great with one failure to feed which could have been caused by the way I was firing it.
The P32 is not a highly refined gun. It has burrs (for lack of a better word), that need to be worked out either by fluff and buffing it or firing it a lot. I think this is the price you pay for the relatively low cost (you have to shop around though as some dealers are getting greedy).
I would suspect that owners who are satisfied with it are about equal to owners of Glocks or other pistols with the cavet that the more you pay for a gun, the higher your expectations are. There will always be lemons and there will always be people for whom the gun is not a good fit.
On the whole, count me as satisfied.
