KRISS USA, formerly known as Transformational Defense Industries (TDI), is an American firearms manufacturer founded in 2006 by French engineer Renaud Kerbrat. The company is best known for the innovative KRISS Vector platform—a series of submachine guns and pistol-caliber carbines featuring the patented Super V Recoil Mitigation System, which redirects recoil forces downward to substantially reduce muzzle climb and felt recoil kriss-usa.com+8en.wikipedia.org+8centerfirereserve.com+8.

Company Highlights:

• Founded: 2006 (design phase), with production beginning around 2009 .

• Technology: The Super V system uses an off-axis bolt and a low-mass carrier to channel recoil energy away from the shooter's shoulder, enabling better control during rapid fire .

• Product Range: Includes the original Vector SMG, rifle-length carbines (CRB), compact piston-driven versions (SDP and SBR), and a .22 LR variant for training and recreation kriss-usa.com+8en.wikipedia.org+8kriss-usa.com+8.

• Evolution: Newer “Gen II/III” models introduced improved ergonomics, modularity, caliber swaps, and optics-ready features en.wikipedia.org.

Why They Stand Out:

• Recoil Innovation: The Super V system offers significantly smoother shooting experience compared to traditional blowback or gas-operated PCPs.

• Versatility: Accepts Glock-compatible magazines and is available in various calibers (.45 ACP, 9 mm, .40 S&W, 10 mm, .22 LR).

• Adoption: Popular among competitive shooters, law enforcement, and gun enthusiasts for its controllable handling and tactical flexibility.
