A have a Kel-Tec CNC inc, P-32/P-3At grip extension. Does not add any capacity, its part number #309 from keltec. I ordered this in the mail, and then sold my P-3AT before it arrived; I now have an LCP and it does not fit on there (after the recall maybe not the best idea I ever had). Anyways, I will mail it someone for free, just PM me your address and its all yours.
