The Kriss Vector SDP 45 ACP Gen 3 (brand part no. KV45-3PRD01) is the lightest, most agile member of Kriss‘s Vector family, a compact semi-auto pistol built for personal protection and home defense. Its redesigned Gen 3 upper and lower housings improve ergonomics and hand support over earlier generations, while an ambidextrous safety and front/rear flip sights keep the controls fast and intuitive under stress. The pistol runs on the Kriss Super V recoil mitigation system that defines the Vector platform, keeping .45 ACP’s recoil impulse flat for quick, controlled follow-up shots. Compatible with full-size Glock magazines, the SDP offers expanded customization options to tailor the platform to any shooter.
