The K100 with an SA/DA trigger mechanism results from meeting the strictest requirements for universal guns, combined with ergonomics suitable for practical shooters and special military units. The front of the frame features a universal tactical Picatinny rail MIL STD 1913. The K100 Mk12 is an upgrade of the well-known Mk6 and Mk7 models, equipped with four removable hand grips. Easily removable, these hand grips make the gun ideal for multi-user shooting practice. Its improved ergonomic design enhances the hand grip during shooting, helping both the shooter's hand and mind stay focused on the target.
