Who This Is For
This magazine is an ideal choice for Glock 43X owners in California and other states with 10-round magazine restrictions who still want a full-size grip advantage. Whether you're a concealed carry permit holder looking for a reliable spare mag, a range shooter who wants a comfortable extended grip, or a home-defense user prioritizing legal compliance without sacrificing ergonomics, this ProMag offers a practical and affordable solution. The extended body also makes a great pinky-grip magazine for users with larger hands who find the standard compact frame too small.

Frequently Asked Questions
Will this magazine fit and function reliably in my Glock 43X?
This ProMag magazine is designed and dimensioned specifically for the Glock 43X slim-frame 9mm pistol. ProMag uses precise manufacturing tolerances and quality-checks every stage of assembly to ensure consistent feeding and reliable function. Please note that this product is not manufactured, authorized, endorsed, or warranted by GLOCK, and GLOCK does not warrant or represent compatibility with third-party magazines. We recommend testing any new magazine at the range before relying on it for carry or defense use.
Why does a 10-round magazine have a 50-round body?
The "10/50" designation means this magazine holds 10 rounds of 9mm ammunition — California's legal limit — but is built within the physical dimensions of a 50-round body. This extended body provides a fuller, more ergonomic grip for shooters with medium to large hands, improves control at the range, and functions as a grip extension for a pistol that is otherwise quite compact. The internal spring and follower are set to stop at 10 rounds, keeping it fully compliant with California's magazine capacity laws.
Is this magazine legal to purchase in California?
Yes. This magazine is specifically blocked to a 10-round capacity, making it compliant with California's magazine capacity restrictions, which prohibit the sale and possession of magazines capable of accepting more than 10 rounds. That is why it is listed under our CA Blocked Pistol Mags category. It is sold ready to use within legal limits. If you are purchasing from another state, always verify your local magazine capacity laws before buying.
