Frequently Asked Questions
Will this magazine extension work with my Glock 19 or other compact Glock models?
The Tyrant CNC Mag Extension is specifically designed for full-size Glock magazines used in the Glock 17, 19X, 22, 34, 35, and 45. It is not compatible with the standard compact Glock 19 magazine. It also does not work with Pmags or factory 10-round restricted magazines, so be sure your existing magazine is a standard-capacity OEM Glock mag for the supported models before purchasing.
Does this extension affect magazine reliability or feeding?
Tyrant CNC includes a new power spring with every extension to maintain reliable feeding even with the added rounds. The aerospace-grade aluminum construction also provides enough weight to ensure the magazine drops free cleanly when released — a critical feature in competitive and defensive shooting scenarios. When properly installed on a compatible Glock magazine, function and reliability should be equivalent to a factory setup.
Are there capacity restrictions I should be aware of for this product in California?
Yes. California law restricts magazine capacity to 10 rounds for most firearm users. Because this extension increases capacity beyond the legal limit when installed on a standard Glock magazine, it may not be legally usable as intended in California. We strongly recommend consulting California's current firearm laws or speaking with a qualified legal professional before purchasing or using this product in the state. Goodland Guns is committed to helping customers stay informed and compliant.
