KRISS USA Vector Sdp Pstl .45 ACP 5.5" Threaded Barrel Pistol

The KRISS USA Vector SDP Pistol in .45 ACP with a 5.5-inch threaded barrel represents a purpose-built platform for operators and shooters demanding recoil management and modularity in a semi-automatic pistol format. Designed for law enforcement, military personnel, and serious civilian shooters, this Vector SDP variant addresses the need for a full-powered .45 ACP pistol that mitigates muzzle rise through KRISS's proven Super V Recoil Mitigation System.

The substantial weight of 10.81 pounds anchors recoil impulse and provides exceptional stability during rapid fire sequences. The proprietary Super V system uses a unique mechanical action that redirects bolt carrier energy downward rather than rearward, resulting in measurably reduced muzzle climb compared to conventional blowback designs. The 5.5-inch barrel length balances velocity retention and handling characteristics, while the threaded muzzle accepts suppressors, compensators, and brake devices without additional adapters.

Polymer lower receiver construction reduces overall weight without compromising durability, while the robust bolt and carrier group handle the higher pressures of .45 ACP ammunition reliably across loading variations. This pistol benefits operators looking for a reliable and effective firearm for tactical applications and precision shooting disciplines.
