Frequently Asked Questions

Is this magazine permanently blocked to 10 rounds or can it be converted?

This magazine is sold as a California-compliant 10-round capacity magazine. It is designed and sold for use in states that restrict magazine capacity to 10 rounds. Goodland Guns sells this product in its compliant configuration, and it should only be used within the bounds of applicable state and local laws.

Will this magazine fit flush with my Glock 19 or 26, or will it extend past the grip?

Because this is a 10-round blocked magazine in an 18-round body, it will extend beyond the grip frame of a compact Glock 19 and subcompact Glock 26 — similar to how a full-size magazine would fit those models. It inserts and locks in securely, but expect a magazine extension below the grip. It fits flush and naturally in the full-size Glock 17.

How does ProMag's reliability compare to factory Glock magazines?

ProMag magazines are made in the USA with heat-treated chrome silicon springs and multi-stage quality inspections, offering solid performance for range use and training. While OEM Glock magazines remain the gold standard, ProMag provides a cost-effective, warrantied alternative that many shooters find dependable for regular use. As with any aftermarket magazine, we recommend testing it with your specific firearm before relying on it for defensive purposes.
