Nick already gave us an update from SHOT Show’s Range Day about the KRISS Vector being offered with an SB Tactical arm brace and in a few new calibers, but we gleaned a bit more info later in the week. First, add 10mm to the list! Vectors will soon be available in .45 ACP, 9×19, .40 S&W, .357 SIG, and 10mm Auto. Sweet. They’re also being offered in a handful of colors, and I’ll admit to liking the look of the white one (pics follow). As seen in the video above, even at a blistering cyclic rate of 1,050 rounds per minute, it’s pretty darn controllable in 9mm. However, it did suffer a handful of stoppages, seen in the uncut video below . . .
