Jeff, you're right in that the P-32 is smaller, but the Rohrbaugh is a LOT smaller than a PPK .380, I believe, but I don't know if the PPK .32 is smaller than a PPK .380. Weight wise, the Rohrbaugh is about the same as a Kel Tec P11.a Rohrbaugh is not smaller than a P32. Smaller than an ASP, about the size of a Walther PPK, only lighter.
I imagine that a P-32 weighing as much as a P-11 would seem like a Kahr MK-9. I'm anxious to get my hands on a Rohrbaugh!
