Frequently Asked Questions
Will this magazine fit and function reliably in my FN FNX-45?
Yes, this ProMag magazine is specifically designed for the FN FNX-45 chambered in .45 ACP. It is engineered to drop free cleanly and feed reliably using the same dimensions as the factory magazine. As with any aftermarket magazine, we recommend a break-in period of several range sessions to ensure optimal spring tension and feeding performance.
Why does this have a 20-round body but only hold 10 rounds?
This magazine uses a 20-round body that has been permanently blocked to hold a maximum of 10 rounds, making it compliant with California's magazine capacity restrictions. The blocking is factory-installed and cannot be reversed without permanently altering the magazine. This design lets California residents enjoy the ergonomic profile of a full-size magazine while staying within the law.
Is this magazine legal to purchase in California?
Yes. Because this magazine is permanently blocked to a 10-round capacity, it complies with California's restrictions on ammunition feeding devices. It falls into the "CA Blocked Pistol Mags" category and is sold legally in California. If you are purchasing from outside California, please verify your local magazine capacity laws before ordering, as restrictions vary by state and municipality.
