All the "rumors" of a new Kahr P40 were enough to make me go straight to the source... here's my e-mail from kahrcs1@aol.com (Kahr customer service )
The P40 is in the beginning stages of production. I have not heard or seen of
any plans to make an MK polymer. The P40 should be available within the next
few months. Providing testing and manufacture goes as planned.
Thank You
Kahr
