Frequently Asked Questions

Will this magazine work in all Glock 20 generations?

This magazine is designed specifically for the Glock 20 chambered in 10mm Auto and is compatible with Gen 1 through Gen 3 variants. If you own a Gen 4 or Gen 5 Glock 20, it will still function, though Gen 4/5 pistols ship with their own updated magazine bodies. Always confirm fitment with your specific generation before purchase.

Why does a 10-round magazine have a 15-round body?

This is a California-compliant "blocked" magazine. The physical body is the same as the standard 15-round Glock 20 magazine, but it has been permanently or semi-permanently restricted to hold no more than 10 rounds to comply with California's magazine capacity laws. This design allows the magazine to sit flush and function identically in the firearm while remaining legal for California residents.

Is this a factory Glock magazine or an aftermarket product?

This is a genuine, factory-original Glock magazine — not an aftermarket clone. It is manufactured to Glock's exact tolerances using a hardened steel feed lip insert encased in high-tech polymer, ensuring the same reliability and drop-free fit you'd expect from any OEM Glock accessory. For best performance and longevity, always choose factory Glock magazines over imitations.
