ProMag Springfield XD40 Magazine .40 S&W Blued Steel 11/rd

The ProMag Springfield XD40 Magazine .40 S&W Blued Steel 11-Round is a purpose-built replacement and spare magazine for Springfield Armory XD pistols chambered in .40 S&W. Built from heat-treated blued steel with a proprietary DuPont Zytel-based polymer follower lock-plate and base-plate, this 11-round magazine delivers the durability and reliability required for duty carry, training, and competition use. Made in the U.S.A., it combines American manufacturing with proven metallurgical standards that withstand repeated load cycles and field conditions.

The magazine's construction uses chrome-silicon wire wound into a spring that is heat-treated for strength and consistent feeding reliability. The blued-steel body resists corrosion better than bare metal in humid or salt-air environments, while the reinforced polymer base and follower lock-plate provide impact resistance and prevent deformation under carry stress. The 11-round capacity maximizes loadout potential while maintaining compatibility with standard XD40 pistols. This capacity-to-size ratio is familiar to law enforcement and civilian operators who run the XD platform as a duty or off-duty sidearm, allowing for practical mag-change drills and staged magazine staging across duty belts or range bags.

Operators, LEOs, and defensive shooters stockpile spare magazines to eliminate single-point-of-failure risk during extended range sessions, low-light training, or duty rotations. The XD40 platform has maintained a solid footprint in law enforcement and civilian defensive communities, and this ProMag offering provides a cost-effective way to maintain multiple loaded magazines without the premium pricing of OEM alternatives. Whether replacing worn magazines from years of service or building out a complete spare-magazine battery, the ProMag XD40 11-round magazine delivers predictable feeding and long-term reliability at field-proven standards.
