Frequently Asked Questions

Will this magazine fit all Springfield Armory XD models chambered in .40 S&W?

This ProMag magazine is designed to be compatible with standard Springfield Armory XD pistols chambered in .40 S&W. It is always recommended to verify your specific XD variant (such as XD Subcompact vs. full-size) before purchasing, as grip frame dimensions and magazine well tolerances can vary between models. Full-size and service-length XD frames are the primary intended fit.

Is this magazine legal to purchase and use in California?

Yes. This magazine is blocked to a 10-round capacity, making it compliant with California's magazine capacity restrictions. It is sold through Goodland Guns specifically as a California-compliant option. The 20-round body provides a full-size feel and improved grip, while the internal block ensures the magazine cannot hold more than 10 rounds.

How does the ProMag spring design improve feeding reliability?

ProMag uses precision-wound springs made from heat-treated chrome silicon wire, which provides consistent tension and resilience over thousands of load/unload cycles. This spring formulation resists fatigue and deformation better than standard carbon steel springs, helping to ensure reliable chambering and reducing the risk of failure-to-feed malfunctions during use.
