The KRISS Vector SDP Gen 3 pistol is the lightest and most agile member of the Vector family, chambered in .45 ACP and fed by full-size Glock magazines (brand part no. KV45-3PRD00). What sets it apart is the Super V Recoil Mitigation System, which redirects recoil energy downward rather than straight back into your hand, cutting muzzle rise to a degree that has to be felt to be believed. KRISS fully redesigned the Gen 3 upper and lower housings for better ergonomics, improved hand support and more mounting options. The result is a compact, controllable platform that suits personal protection and home defense, and one that will happily eat a 30-round magazine faster than you expect. The threaded barrel leaves the door open for a suppressor down the road.

Key Specifications

• Chambered in .45 ACP, delivering heavy, subsonic-friendly projectiles well suited to suppressed use.
• Standard capacity is 30 rounds using full-size Glock pattern magazines.
• The barrel measures 5.5 inches, keeping the overall package compact and quick to maneuver indoors.
• Barrel material is 4140 chrome moly steel, a tough alloy chosen for long service life under high round counts.
• The barrel wears a black nitride QPQ finish for hardness and corrosion resistance inside and out.
• The muzzle is threaded .578×28, the common pitch for .45 caliber suppressors and muzzle devices.
• It runs a closed-bolt delayed blowback action, which improves accuracy over a simple open-bolt design.
• The Super V Recoil Mitigation System vectors recoil downward to dramatically reduce muzzle climb.
• The trigger is a pivoting single stage unit with a consistent, predictable break.
• Front and rear flip-up sights come standard and stow out of the way when an optic is mounted.

Frequently Asked Questions

Is this an NFA item? No. The SDP is configured as a pistol with no shoulder stock, so it transfers as an ordinary Title I handgun with no ATF tax stamp required.

What magazines does it use? Full-size Glock .45 ACP magazines, which makes spares easy and inexpensive to find.

Are the controls ambidextrous? Yes. The Gen 3 Vector uses ambidextrous controls so it runs the same from either shoulder.

Nothing else on the market handles .45 ACP recoil the way the Super V system does, and once you have shot one the flat-tracking muzzle is hard to give up. Pair it with Glock magazines you probably already own and a suppressor if you go that route.
