Key Features
- Closed-bolt delayed blowback system – This reduces felt recoil and muzzle rise, letting you keep sights on target for faster follow-up shots. Why it matters: You shoot faster, more accurately, and with less fatigue.
- 5.5-inch threaded barrel with black nitride finish – The threading allows suppressor or compensator mounting, and the QPQ coating resists corrosion and wear. Why it matters: You get ready-to-suppress performance with extended barrel life.
- Flat Dark Earth polymer frame – Durable, lightweight, and low-glare. Why it matters: It blends in with gear and doesn't show holster wear as easily as black.
- Full-size Glock magazine compatibility – Uses common, affordable, and reliable 9mm Glock sticks (17/19/34). Ships with a 40-round mag. Why it matters: You can use your existing Glock mags or buy spares anywhere.
- Modular handguard with M-Lok slots – Lets you attach lights, lasers, or grips. Why it matters: You can customize the setup for home defense, range use, or competition.

This pistol is for shooters who want the Vector's unique operating system in a compact package. It's ideal for home defense, range plinking, or as a truck gun. New gun owners will appreciate the low recoil; experienced shooters will like the Glock mag compatibility and suppressor-ready barrel.
