In the realm of firearms, reliability and consistency are paramount. The ProMag extended magazine for the Springfield Armory XD pistols in .40 S&W caliber stands as a testament to these principles. Crafted with precision in the United States, this magazine extends your capacity to 20 rounds, ensuring you have ample firepower at your disposal.
The construction is robust yet refined—heat-treated blued-steel forms the backbone of this magazine. This choice of material not only offers durability but also resists wear over time. Complementing this sturdy frame are components made from proprietary DuPont Zytel-based black polymer. These include a follower lock-plate and base-plate that contribute to seamless operation under various conditions.
A key feature lies within its core: a spring expertly wound from chrome-silicon wire, which undergoes rigorous heat treatment for enhanced strength and reliability. Each stage of assembly is meticulously checked and double-checked, reinforcing ProMag's commitment to quality—a promise backed by their lifetime guarantee against any manufacturer's defects.
Measuring an overall length of 8.125 inches, it integrates smoothly with your firearm without compromising balance or handling characteristics. Whether you're on duty or at the range, trust in ProMag’s craftsmanship to deliver performance when it matters most.
