Key Features
- Redesigned Gen3 Housings – The upper and lower are reshaped to improve hand support and allow more customization with aftermarket parts. Why it matters: You get a more comfortable, secure grip and the freedom to tailor the pistol to your needs.

- M-LOK Handguard with Picatinny Rail – The free-floating handguard offers M-LOK slots at 3, 6, and 9 o’clock, plus a short Picatinny rail at the top. Why it matters: You can mount lights, lasers, or grips exactly where you want them without bulky adapters.
- 33-Round Magazine Included – Comes with a full-size Glock-style 33-round magazine, plus a cleaning kit and cable lock. Why it matters: You get more capacity out of the box, fewer reloads at the range, and everything you need to start shooting right away.
Who It’s For
This pistol is built for shooters who want a compact, high-capacity handgun with serious power. If you’re setting up a home defense gun, need a reliable truck gun, or just want a range toy that turns heads, the Vector SDP G3 fits the bill. It’s also a great pick for anyone who already owns Glock 10mm magazines—they work here too.
Pros and Cons
- Pros: Unique, low-recoil action; accepts common Glock mags; threaded barrel and M-LOK handguard for customization; 33-round capacity; flat dark earth finish looks great.
- Cons: The manual safety can be stiff out of the box—expect a break-in period of about 100 rounds to smooth it out. Also, the 10mm recoil is stout, so new shooters may want to start with lighter loads.

Frequently Asked Questions
Does this pistol use Glock magazines?
Yes, it accepts full-size Glock-style 10mm magazines. The included 33-round mag is made by KRISS but is fully compatible with Glock 20/40 mags. That means you can use standard or extended Glock mags interchangeably.
What thread pitch is the barrel?
The barrel has a 1/2×28 thread pitch, which is common for 9mm and .40/10mm suppressors and compensators. You’ll find plenty of aftermarket muzzle devices that fit without adapters.
Is this legal in my state?
Most states allow this pistol as a semi-auto handgun, but check your local laws regarding threaded barrels and magazine capacity. We ship to all 50 states, but we follow all federal and state regulations.
How does the Super V action reduce recoil?
KRISS’s Super V system uses a delayed blowback action that redirects the bolt’s energy downward, reducing muzzle climb and felt recoil. You’ll notice it’s much flatter shooting than a traditional 10mm pistol, especially during rapid fire.
