The Kriss Vector G2 SDP-E is a .45 ACP semi-automatic pistol with a 6.5-inch threaded barrel and the Kriss recoil mitigation system, which directs the bolt's recoil impulse downward rather than rearward. This significantly reduces felt recoil and muzzle rise for .45 ACP. Capacity is 13 rounds standard (15+1 with optional extended magazine). Overall length is 16.75 inches, weight is approximately 5.9 lbs, and the finish is matte black.

Features 

 
The Kriss recoil mitigation system is the central engineering feature. The bolt travels downward on firing rather than rearward, which reduces perceived recoil substantially compared to a conventional .45 ACP pistol. The threaded 6.5-inch barrel accepts suppressors and other muzzle devices. Low-profile flip sights fold out of the way when mounting optics. An ambidextrous manual safety accommodates both shooters. The polymer frame is light for the platform's overall size.

The Vector's distinctive recoil system is what most buyers come for, and owners generally confirm it works as advertised. The downward bolt travel makes .45 ACP noticeably softer to shoot. Accuracy gets positive remarks, and build quality is considered solid.

The most common criticisms are size and weight. At 5.9 lbs and 16.75 inches, this is not a carry pistol, and buyers who expected something more compact are sometimes surprised. The price point also generates discussion. Some feel the unique mechanism justifies the cost, others compare it to what they could get in a conventional .45 ACP pistol at a lower price. Aftermarket holster availability is limited, which affects practical carry options. New shooters report a learning curve with the operating system relative to conventional semi-autos.
