KRISS Vector SDP G3 .45 ACP | 5.5 in

The KRISS Vector SDP G3 in .45 ACP is a compact, semi-automatic platform with a 5.5-inch barrel and Arctic Delta Cerakote finish. It uses a closed-bolt delayed blowback operating system and ships with one 10-round magazine. A compact red-dot such as a Holosun 507K pairs well with this platform and remains comfortably under $1,000 for a durable, handgun-mounted optic solution.
