Detailed Features
The KRISS Super V delayed blowback system redirects bolt mass downward rather than rearward, which reduces muzzle rise noticeably on a .45 ACP platform. The pivoting single-stage trigger has a consistent pull. Ambidextrous safety and magazine release work for both hands. Adjustable flip sights on front and rear. The Vector takes Glock G21 magazines, which broadens sourcing options. Advanced polymer furniture keeps weight manageable for what it is.
Usage
The Vector SDP's size and weight make it a range gun and collector piece more than a carry option. In .45 ACP with 13+1 capacity and a closed-bolt design, it shoots very flat for the caliber. Competition shooters and enthusiasts looking for something mechanically distinct from a conventional pistol tend to gravitate toward it.

What Reviewers Say
Quoted verbatim from YouTube reviews. Each link opens the video at the moment quoted.
Blowback operation is the standard operation for 9mm pistol caliber carbines. It's very reliable and cheap and easy to make. However, it's not really ideal because it adds a lot more recoil than you really need.
We have a magazine release right here, which can be a bit of an issue if you are not holding it correctly.
The trigger here is a subgun trigger. However, it is considerably better in my personal opinion than the MP5.
Really nice pull. And it's got a quick reset as well. And that allows you to have really quick follow-up shots, which is what you want for a subg gun.
I thought it would be a little too rusty to hit those small targets with a 9mm PCC, especially considering you get some drop there at 100 yards. But super accurate.
Customers Say
AI-generated insights derived from customer reviews and discussions on popular gun-enthusiast forums.
The KRISS Vector SDP Gen II .45 ACP generates polarized reactions, which is about what you'd expect from a firearm this unconventional.
The recoil management is the most praised feature. Owners consistently report that the Super V system keeps muzzle rise well controlled for .45 ACP, and follow-up shots come back on target faster than with conventional pistols. The compact frame and Glock G21 magazine compatibility are practical advantages. Customization options through aftermarket accessories are a draw for enthusiasts.
On the critical side: weight at 5.9 lbs is significant for a pistol, and the size makes it impractical for concealed carry. Some owners have reported feeding issues with specific ammunition, though most describe reliability as acceptable with quality loads. The price draws scrutiny when compared to more conventional .45 ACP pistols. Maintenance is more involved than a straightforward tilting-barrel design. Parts availability concerns come up for buyers who plan to customize heavily.
