Frequently Asked Questions
Which exact Glock models does this magazine extension fit?
The Tyrant CNC Mag Extension is designed to fit factory Glock magazines for the Glock 17, 19X, 22, 34, 35, and 45. It does not fit Magpul PMAGs or factory 10-round restricted magazines. If you're unsure whether your specific magazine is compatible, check that it is an OEM Glock double-stack magazine for one of the listed models.
Does this extension require any tools or gunsmithing to install?
Installation is straightforward and requires no special tools or gunsmithing. Simply disassemble your existing Glock magazine, swap out the base pad with the Tyrant CNC extension, and replace the spring with the included power spring. The upgraded spring is included specifically to ensure reliable feeding with the increased round count.
Are high-capacity magazine extensions like this legal in California?
California law restricts magazines to a maximum of 10 rounds. Because this extension adds 6 rounds to 9mm magazines and 5 rounds to .40 cal magazines, the resulting capacity would exceed the 10-round limit and is not legal for most California residents to purchase or possess. Buyers in California should verify current state and local regulations before ordering. Goodland Guns complies with all applicable California firearms laws.
