The Velocity Magazine Extensions for Glock Magazines are designed and manufactured here in the USA by Falkor Defense. These aluminum magazine extensions are designed to let the shooter move quickly with the magazines and let the magazines themselves move quickly when dropping free from the mag well… oh, and they add 4 more rounds of capacity for 9mm magazines (2 more for .40 S&W).
The shape of the extension gives plenty surface area for the shooter to manipulate during malfunction clearances, reloads with retention, and other tasks that require a firm grip on the magazines. The weight of the extension ensures that the magazines drop free of the magazine well quickly during speed reloads.
The Velocity Magazine Extensions from RE Factor Tactical are available in an exclusive OD Green anodized color with the REFT TNT logo. Check them out at REFactorTactical.com.
