The Kriss Vector SDP Enhanced is a semi-automatic pistol chambered in 9mm, built around the Vector's delayed blowback action and Super V recoil mitigation system. The 6.5-inch barrel and 16.75-inch overall length make it a large pistol -- closer to a PDW in size. At 5.9 lbs it's substantially heavier than a conventional service pistol. The OD Green polymer finish covers the frame and furniture.

  The Super V system is the defining mechanical feature -- the bolt carrier travels downward into the pistol grip on firing rather than rearward in line with the bore, which reduces the lever effect that causes muzzle rise in conventional pistols. The SDP classification means it has no shoulder stock. Accepts Glock 17-pattern magazines.

The Vector SDP in OD Green draws a specific buyer: someone who wants the Super V platform's recoil characteristics in 9mm and appreciates the distinctive look. Those who buy it for the intended purpose -- minimizing muzzle rise and felt recoil -- are largely satisfied with how it performs in that respect. The difference in muzzle rise compared to conventional pistols is noticeable and real.

At 5.9 lbs and 16.75 inches overall it's not a practical carry gun, and most owners use it as a range gun. The size and weight aren't complaints from buyers who knew what they were purchasing; they're surprises for buyers who underestimated the dimensions from photos.

Reliability gets mixed reports. Most owners report reliable function after break-in; a portion note feeding issues, particularly in early round counts, which the manufacturer typically addresses under warranty. Proper maintenance cadence matters more with this platform than with simpler gas-operated or recoil-operated pistols.

Price is consistently noted as high for the category. Aftermarket accessories exist but the selection is narrower than for common platforms. OD Green finish gets positive marks from buyers who wanted a tactical aesthetic that differs from standard black.
