The Kriss Vector Gen II SDP is chambered in 10mm Auto and runs a closed-bolt delayed blowback system that noticeably flattens recoil compared to a straight blowback design. The 5.5-inch barrel sits in a 16.75-inch overall package weighing 5.9 lbs. Capacity is 15+1 rounds from a standard magazine.

Features 

 
The barrel is 4140 Chrome Molybdenum Steel with a Black Nitride (QPQ) finish for corrosion resistance. Ambidextrous safety and flip-up sights accommodate left- and right-handed shooters without modification. The standard polymer grip keeps the weight down while maintaining a secure hold during rapid fire. 
 
The delayed blowback action is the distinguishing mechanical choice here. It redirects bolt energy downward on firing, which cuts muzzle rise and lets follow-up shots land closer together than most 10mm platforms.

The Vector Gen II draws consistent praise for its recoil management system. Owners who shoot 10mm regularly note that the muzzle stays flatter than on conventional pistols in the same caliber, which makes it genuinely easier to shoot fast and accurately.

Ergonomics are well-regarded. The grip angle and overall balance feel comfortable for extended sessions, which is appreciated given the heavier 10mm round. The 15+1 capacity in a handgun-size package is a plus for people who want substantial firepower without a full rifle.

On the negative side, weight and bulk come up. At 5.9 lbs it is heavier than most comparable designs, which matters for anyone considering carry. The price is on the high end for the category, and aftermarket holster selection is limited compared to more common platforms. Shooters new to 10mm sometimes find the recoil more than they expected even with the system's mitigation.
