Owners of the KRISS Vector platform tend to comment first on the recoil impulse. The Super V system in the SDP shifts the perceived recoil down and back rather than straight up, and most shooters describe the .45 ACP version as noticeably flat and easy to keep on target compared to a typical blowback pistol in the same caliber.

The unconventional shape draws mixed reactions. Some find the Vector's balance and low bore axis make it very controllable, while others say the housing feels bulky for a pistol and takes some adjustment to grip properly. Using Glock-pattern magazines is generally seen as a plus, since spare mags are cheap and widely available.

Build quality feedback is mostly positive, with owners noting the housings feel solid, though a few mention the trigger is heavier than they'd like out of the box and often gets swapped for an aftermarket kit.
