The PF-9 retains the best features from our P-11 and P-3AT pistols combined into the flattest and lightest single stack 9mm configuration ever made. The barrel, locking system, slide stop, assembly pin, front sight, recoil springs and guide rod are adapted from the P-11. The PF-9 is nearly identical to the P-11 in length and height and shares the same exterior controls. The shorter trigger system with integral hammer block and the extraction system are adapted from the P-3AT. Just like the P-11, the PF-9 will accept +P ammunition, however, not with continuous use.
The rear sight is a new design and is adjustable for windage with the supplied allen wrench as well as for elevation with the use of shims (not included). The included 7 round rectangular magazine is supplied with a finger extension base plate and numbered holes. The under barrel accessory rail shares the dimensions of the MIL-STD-1913 picatinny rail although there is only one locking notch in the forward position.
