Taking things a step further, the .30-caliber 7.5 FK continues this legacy and is now chambered in its most compact firearm yet, the FK Brno PSD-C. Carrying the namesake of the Czech city where it is made, the FK Brno PSD-C (short for Police Sport Defense–Compact) is a semi-automatic, centerfire, repeating pistol. As of this writing, there are only three loads of 7.5 FK ammunition, so it can be tough to source. To that end, 7.5 FK ammo must be purchased from FK Brno’s importer, the Italian Firearms Group, or its stateside manufacturer, Tascosa Machine & Tool. Testing concluded by swapping the 7.5 FK barrel back in and firing at a bevy of Caldwell animal silhouettes placed out to 150 yards.
