Description
There is nothing else on the gun shelf that looks or shoots like a Vector. The Kriss Vector CRB G3 in .45 ACP is built around the Super V Recoil Mitigation System, a closed-bolt delayed blowback design that redirects bolt mass downward instead of straight back into your shoulder. The result is a big-bore carbine with noticeably less muzzle rise than you would expect, which means faster follow-up shots and a more pleasant day at the range. This Gen 3 model wears a 16 inch barrel, a fixed black polymer stock, and ships with one 10-round magazine.
What the Gen 3 Vector CRB Brings to the Table
Kriss reworked the upper and lower housings for this generation, and the improvements are practical ones. The lower has reshaped side profiles and fresh texturing on the mag well for a more secure hold, and the trigger is a crisp single-stage with minimal pre-travel. The square shroud carries M-LOK slots on the sides and bottom for lights and hand stops, while the full-length Picatinny top rail gives you plenty of room for a red dot or magnified optic. Low-profile flip-up front and rear sights come installed, so you can shoot it the day you bring it home. The ambidextrous short-throw safety keeps controls friendly for lefties too.
A .45 ACP Carbine That Feeds From Glock Mags
Magazine compatibility is one of the smartest things about this platform. The Vector CRB feeds from full-size Glock pattern .45 ACP magazines, so if you already run a Glock 21, your mags carry right over. The 16 inch barrel is 4140 chrome moly with a Black Nitride finish for wear and corrosion resistance, and it comes threaded .578×28 for a muzzle device or suppressor. At 7.7 pounds unloaded with an overall length of 35.37 inches, it balances well and handles quickly for a rifle-length gun.
Takedown is simple thanks to tool-less pin disassembly, cleanup is quick, and the whole package is well suited to PCC matches, plinking sessions, and anyone who just wants a .45 that is genuinely fun to shoot.

Frequently Asked Questions
Does the Kriss Vector CRB G3 use Glock magazines?
Yes, this .45 ACP model feeds from full-size Glock pattern magazines, the same type used by the Glock 21. If you already own a Glock in .45, your existing mags will run in the Vector. Extended Glock-pattern .45 mags fit as well where capacity allows.
What makes the Super V recoil system different from a normal blowback carbine?
Most pistol-caliber carbines use straight blowback, which sends all the bolt energy straight back at you. The Vector's Super V system uses a closed-bolt delayed blowback design where the bolt mass moves down and behind the magazine well during cycling. That redirects recoil energy away from your shoulder and keeps the muzzle flatter, which is a big part of why the Vector shoots so soft for a .45.
Is the barrel on this Vector CRB threaded for a suppressor?
It is. The 16 inch barrel comes threaded .578×28 RH, which is the standard pitch for most .45 caliber muzzle devices and suppressors. The 4140 chrome moly barrel also gets a Black Nitride finish for added durability.
Can I mount a red dot on the Vector CRB G3?
Absolutely. The full-length Picatinny top rail accepts red dots, magnifiers, or low-power variable optics, and the included flip-up sights fold down out of the way or can co-witness depending on your setup. The Gen 3 M-LOK shroud adds mounting real estate on the sides and bottom for lights and other accessories.
