The Kriss Vector Gen II SDP is a semi-automatic pistol chambered in .45 ACP. It uses a blowback operating system and ships with a 13+1 capacity. The FDE polymer grip is the same Flat Dark Earth Cerakote finish as the rest of the gun, and the ambidextrous safety works equally well from either side.

Detailed Features 

The blowback system reduces felt recoil relative to most .45 ACP pistols, which shows up in faster split times at the range. Low-profile flip-up front and rear sights fold down when not needed. Integrated Picatinny rails front and top allow lights, optics, and other accessories without additional hardware. The Vector's overall length (16.75") puts it in pistol-carbine territory. It handles differently from a compact carry gun, which is worth knowing before buying. 
 

Usage Scenarios 

At a range session the 13+1 capacity and reduced recoil make for comfortable extended shooting. For home defense the capacity is adequate and the rail system lets you mount a light. The gun is not well-suited for concealed carry given its size and 5.90 lb. weight.

Owners generally respond well to the Vector's appearance and the FDE Cerakote finish. The low recoil is the most consistently praised functional feature. Shooters moving from standard .45 ACP pistols often notice the difference right away, and it makes the gun accessible to those who find heavier recoil tiring.

The integrated Picatinny rails get positive marks from buyers who want to run lights or optics without extra adapters. On the critical side, the size and weight come up often: at 5.90 lbs. and 16.75" overall, it is not a carry gun, and some buyers find it bulkier than expected. The unconventional operating system takes some time to get familiar with.

Reliability is generally reported as good, though some users have seen issues with specific ammunition. Proper maintenance and sticking to quality ammo brands resolves most of those complaints. Overall sentiment leans positive among buyers who understand what the platform is. Those who approach it expecting a conventional pistol are more likely to be disappointed.
