Classic Firearms goes over the Kriss Vector SDP Gen 3, comparing it against the older Gen 1 and Gen 2 models and demonstrating its performance in 9mm, .45 ACP, and 10mm calibers. They talk about the firearm's unique "Super V" recoil mitigation system, a feature that directs the bolt carrier downward to centralize the recoil impulse, contributing to its reputation for high cyclic speed in full-auto. They highlight the significant generational improvements in the Gen 3, which include a shorter charging handle, a more ergonomic and shielded magazine catch, an improved trigger, and the adoption of a 1913 rail interface for the folding stock.
