The Kriss Vector SDP G3 in .45 ACP (brand part no. KV45-3P2T00) is a Two-Tone pistol that carries the Vector’s Super V recoil system into the third generation. Kriss describes the SDP as the lightest and most agile member of the Vector family, aimed at personal protection and home defense. The 5.5-inch barrel is threaded .578×28, and the redesigned Gen 3 housings add better hand support and more room for customization. It is compatible with full-size Glock magazines, which makes magazine sourcing simple.

What magazines does the Vector SDP G3 use? Kriss states the Gen 3 SDP is compatible with full-size Glock magazines, and one 30-round magazine is included with this .45 ACP model.
