The Kel-Tec Pf-9 pistol is a small form factor 9mm with a single-stack 7 round pistol. It’s thin size allows for easy concealed-carry performance.
To achieve highest operator safety, combined with ease of handling, the pistol is “double-action only”. It has no safety and the hammer is never fully cocked. This means that with the PF-9 pistol, the action of pulling the trigger performs both the cocking and firing actions.
