Kriss TDI | Vector SDP Gen3 9mm 5.5″ | KV903PWD00

The KRISS Vector SDP Gen3 is a compact, semi-automatic pistol built around the Vector platform with a redesigned upper and lower for improved ergonomics and modularity. This configuration ships with a 5.5-inch black nitride threaded barrel, M-LOK handguard and full-length Picatinny top rail for optics and accessories. Designed to accept full-size Glock-style magazines, it is intended for personal protection and for range training or practical shooting applications. A compact red-dot such as a Holosun 507C pairs well with the full-length Picatinny rail and stays well under $1,000.
