Kriss TDI | Vector SDP KV45-PFD20 | .45 ACP 5.5″ FDE

The KRISS Vector SDP KV45-PFD20 is a .45 ACP semi-automatic pistol built around the manufacturer’s Super V recoil mitigation architecture and a closed-bolt, delayed-blowback operating system. It features a 5.5″ threaded barrel, full-length MIL-STD 1913 Picatinny rails top and bottom, low-profile folding sights, and an FDE polymer grip with an alloy frame. For a compact red-dot that pairs well with this pistol and stays under $1,000, consider a Vortex Venom or a comparable compact reflex sight for fast target acquisition.

This platform suits precision range training and competitive pistol disciplines that benefit from rapid follow-up shots and accessory mounting options. The Vector’s compatibility with standard Glock 21 magazines supports magazine commonality with other pistols in that ecosystem.
