Built in the USA, this Vector SDP uses the KRISS Super V closed-bolt delayed-blowback system designed to redirect recoil downward to reduce muzzle rise. It features right-side ejection and an ambidextrous, two-position safety for familiar and straightforward handling.
The 6.5-inch .45 ACP barrel uses a 1:16 RH twist and is threaded, with a protector installed. Thread pitch for this example is not specified. The platform includes a rear single-point sling attachment loop for carry options.
Controls and ergonomics include a left-side folding charging handle and a durable polymer receiver. A full-length top Picatinny rail and a short lower rail segment provide mounting space, and polymer flip-up sights are already installed.
This pistol accepts Glock 21-pattern magazines and ships with two factory 13-round mags for a 13+1 capacity. Receiver markings include KRISS VECTOR, .45 ACP, KRISS USA, VA. BEACH, VA — SDP 45CAL., MADE IN USA, and U.S. patent numbers.
