Reliable magazines are a critical component of any defensive firearms setup. They must feed consistently, resist the elements, and allow fast, confident reloads when it matters most.

Constructed of stainless steel, it features numbered witness holes for quick round-count checks, an extended polymer base pad to aid tactical reloads, and a blacked-out corrosion resistant coating designed to deliver a lifetime of service. Price is $36.99 for shooters seeking a high-capacity, hard-wearing spare. Shop this product

Design and construction
The magazine body uses stainless steel to balance strength and corrosion resistance. That stainless core resists feed-lip deformation under extended use and provides a solid platform for positive feeding. The blacked-out corrosion resistant coating gives extra protection in humid or maritime environments, preserving finish and function over time.
Witness holes and base pad
Numbered witness holes along the magazine body let you visually confirm remaining rounds at a glance — a simple but effective feature for defensive readiness and range management. The extended polymer base pad improves purchase during quick reloads and offers a modest buffer when seating the magazine into the magwell, making tactical transitions smoother.
Performance and tactical considerations
An 18-round capacity provides extra rounds on tap compared with standard magazines, reducing the frequency of reloads in high-stress scenarios. While specific caliber compatibility isn’t listed, buyers should verify fitment with Springfield Armory pistols and platforms before purchase. Springfield Armory is a notable brand with a long history of firearm design, and this magazine reflects that focus on practical, field-ready features.
