The Vector Gen II SDP-SB Black is a semi-automatic pistol chambered in .45 ACP, built around a closed-bolt delayed blowback action. That action is the defining characteristic here. It redirects bolt energy downward rather than straight back, which noticeably reduces felt recoil compared to conventional blowback designs in this caliber.
The ambidextrous safety works equally well for left- or right-handed shooters. Flip-adjustable front and rear sights give you multiple zero options without tools. The 4140 chrome moly barrel with black nitride (QPQ) finish is corrosion-resistant and hard. Glock G21 magazine compatibility means spare mags are easy to find.
At 24.5 inches overall and 6.7 lbs, this is not a compact carry gun. It fits home defense, suppressor-host, and range use better than concealed carry. The 13-inch top rail accommodates most optics and accessory setups. Competitive shooters who want a .45 ACP platform with lower recoil than a straight blowback design will find the delayed-blowback system worth the weight trade-off.
The Kriss Vector Gen II SDP-SB in .45 ACP draws a mix of genuine enthusiasm and practical criticism.
The delayed blowback system is the most talked-about feature. Most owners confirm it delivers meaningfully reduced muzzle rise during rapid fire, which makes the .45 ACP more manageable than you'd expect from a pistol-format gun. Ergonomics and control placement get consistent praise. The grip angle and ambidextrous safety work well for a wide range of hand sizes.
Accuracy gets good marks, particularly at medium distances. Build quality is generally viewed as solid, the materials feel substantial, though a few users have flagged finish wear on specific components over time.
The futuristic profile attracts attention at the range; opinions split between people who like that it looks unconventional and those who find it too busy compared to traditional handguns.
Price is a real friction point. The Vector costs noticeably more than most .45 ACP handguns, and some buyers question whether the recoil reduction justifies the premium over simpler platforms. A smaller subset of owners has reported feeding issues with specific ammunition, which stands out for a gun at this price. The SBR classification question also comes up. This model uses a brace rather than a stock, but buyers in some states still research local regulations before purchasing.
The overall picture: fans of the platform tend to be genuinely enthusiastic, while skeptics point to price and occasional reliability reports as reasons to shop around first.
