ProMag SIG08 8-Round Steel Magazine for Sig P220 .45 ACP

In the realm of firearms, where precision and reliability are paramount, the magazine serves as a crucial component. ProMag has crafted an 8-round magazine for the Sig Sauer P220 pistol chambered in .45 ACP that stands out in its class. This isn't merely an accessory; it's a testament to engineering excellence.

The body of this magazine is constructed from heat-treated blued steel, ensuring durability under rigorous conditions. Each element speaks to meticulous design choices aimed at enhancing performance and longevity. Within, you'll find an injection-molded follower lock-plate and base-plate fashioned from DuPont Zytel-based black polymer—an advanced material known for its resilience and lightweight properties.

At the heart of any reliable feeding system lies the spring. Here, ProMag employs chrome-silicon wire meticulously wound and heat-treated to bolster strength while maintaining flexibility over time. This ensures consistent pressure on cartridges for smooth operation with each cycle.

Crafted proudly in the U.S.A., this magazine embodies American craftsmanship paired with modern materials science—a fusion that delivers unfaltering reliability when it matters most.
