FK Brno first showcased the Field Pistol at the IWA 2015 expo.
The proprietary cartridge is claimed to have an effective range—in terms of accuracy and terminal ballistics—of at least 100 meters (109 yards) for targets of up to 150 kg (330 lbs) while maintaining relatively low recoil and good controllability.
The cartridge produces 842 ft⋅lbf of muzzle energy (1142 J), roughly on par with the 10mm Auto and .357 Magnum.
Available at a much lower price-point, the PSD is lighter and roughly equal to the FK BRNO in performance.
A multi-caliber design, it also shoots the cheaper 9x19mm, 10 mm Auto and .40 S&W ammunition types with a barrel replacement.
