Killer Innovations Velocity Mag Extensions for Glock 17 – Back in Stock (Except Washington)
IMPORTANT LEGAL NOTICE – PLEASE READ BEFORE PURCHASING:
Due to the unconstitutional Bill 5078 passed in Washington State, the sale and possession of “high-capacity magazines” is currently banned within the state.
As a result:
On July 1, 2022, Killer Innovations ceased manufacturing and selling the Velocity Mag Extension within Washington.
As of August 25, 2023, the Velocity Mag Extension has been officially re-released for out-of-state sales only.
If you're outside of Washington, you're cleared hot. If not—check your local laws before buying. IronKells Armory complies with all state and federal regulations.
Product Overview:
The Velocity Mag Extension for Glock isn’t just a pretty piece of anodized aluminum—it’s a full-blown upgrade for shooters serious about fast reloads and added capacity. Engineered by Killer Innovations and trusted by pros, these magazine extensions are built to enhance grip, increase mag durability, and maximize reload speed under stress.
Featuring Killer Innovations' patented Enhanced Grip Feature (EGF) cuts, the mag extensions provide serrated control surfaces on the front and sides—no matter how you grab your mag, you're locked in. That means faster, more consistent reloads, even when adrenaline’s high
Torture tested from 6-foot drops onto concrete, the Velocity Mag Extension laughed in the face of failure. It’s tough, toolless, and made for warfighters, competitors, and serious gun owners.
Toolless Design:
Cleaning your mag is simple—just depress the retaining pin and slide the floorplate out. No tools. No excuses.
