Kriss TDI | Vector SDP G3 | .45 ACP | 5.5″ Threaded | 30rd

The KRISS Vector SDP Gen3 is a semi-automatic pistol built around a compact 5.5-inch threaded barrel and fed by full-size Glock-compatible magazines. This configuration includes an M-LOK handguard, a full-length Picatinny top rail, and low-profile flip-up sights, giving a practical balance of modularity and control for range and competition use. For mounting a red-dot optic under $1,000, consider a compact reflex such as the Trijicon MRO mounted to the Picatinny rail for a low-profile, durable sighting solution.
