Frequently Asked Questions
Will this magazine fit all Sig Sauer MPX variants?
This ProMag magazine is designed to be compatible with the Sig Sauer MPX platform, including the MPX Carbine and MPX Pistol variants chambered in 9mm. As with any aftermarket magazine, we recommend confirming fitment with your specific model before purchasing. If you have questions, our team at Goodland Guns is happy to help.
Is this magazine restricted to 10 rounds permanently?
Yes. This magazine is permanently blocked to a 10-round capacity, making it California-compliant under the state's magazine capacity restrictions. The 50-round body size is retained for ergonomics and grip, but the internal block ensures it cannot hold more than 10 rounds of 9mm ammunition.
How does the ProMag lifetime guarantee work?
ProMag Industries stands behind all of their magazines with a lifetime guarantee covering manufacturer defects in materials and workmanship. If your magazine fails due to a defect — not normal wear or misuse — ProMag will repair or replace it. Contact ProMag directly to initiate a warranty claim, or reach out to Goodland Guns for assistance.
