Frequently Asked Questions
Which Glock models is this magazine extension compatible with?
This Tyrant CNC mag extension is designed to fit factory Glock magazines for the Glock 17, 19X, 22, 34, 35, and 45. It does not work with Magpul PMAGs or any 10-round restricted magazines, so be sure you're running an OEM or compatible full-capacity Glock magazine before purchasing.
Does this extension require any modifications to my existing magazine?
No permanent modifications are required. The Tyrant CNC extension replaces your factory base pad and includes a new power spring rated for the increased capacity. Installation is straightforward and reversible, allowing you to swap back to your original setup if needed.
Are there magazine capacity restrictions I should be aware of in California?
Yes. California law currently restricts magazine capacity to 10 rounds for most firearms. Because this extension is designed to push Glock magazines well beyond 10 rounds, it may not be legal for purchase, possession, or use in California under current state law. Goodland Guns recommends consulting applicable state and local regulations before purchasing any high-capacity magazine accessory.
