The FK BRNO PSD is a multi-caliber pistol designed around the proprietary 7.5 FK round, but able to use 10mm/40 S&W, and 9mm. The engineers who designed this weapon wanted a multi-caliber pistol that enables the user to train with common, less expensive 9mm ammo.

The barrel change requires no tools and can be performed in less than a minute! When combined with the patented stabilizing brace, the pistol transforms into “a rifle on a belt.”

FK BRNO is located in the city of Brno in the Czech Republic, a city known for its firearms manufacturing prowess. While the pistol has some semblance of another Czech pistol (the CZ-75), this one is all FK BRNO!

The 7.5 FK is a bottlenecked rimless cartridge that travels at 2,000 FPS! The manufacturer states that at this speed, their “rapid acquisition system does not require adjustment within the range spectrum.”

The round has a flat trajectory, and the sights shoot to the aiming point up to 100 meters when using the 7.5 FK round. The 7.5 FK was designed for a Middle East private military contractor looking for a pistol that would allow the shooter to engage targets at 100 yards. Although the 7.5 FK is a hot cartridge, the patented recoil attenuation system keeps it all steady by utilizing a tungsten weight attached to the front of the guide rod. The original BRNO field pistol is all steel and costs $7,000. FK BRNO then came out with a polymer framed PSD version at $1,650.

The sight system on the pistol varies. There is a standard three-point sight, a Ring sight that is designed to allow rapid target acquisition, and finally the “Butterfly sight” that is a proprietary FK BRNO design. The fully integrated optics platform is suitable for various model red dot sights.
