When reliability matters—on the range or in a defensive carry setup—spares and replacements are as important as the handgun itself. A robust backup magazine ensures feed consistency, durability, and confidence when you need it most.

PROMAG SPRINGFIELD XD-S is a direct-replacement magazine for the Springfield XDS chambered in 45ACP. It is constructed from heat-treated steel with components molded from Technapolymer, and an antifatigue spring designed to keep the magazine loaded and ready for up to six years. This affordable upgrade at $17.99 gives owners a durable spare that won’t break the budget. Shop this product

Build Quality and Materials

The heat-treated steel body resists deformation under repeated loading and impacts, while Technapolymer components reduce weight and resist corrosion. For defensive use, these material choices balance toughness with everyday carry practicality. The antifatigue spring is a standout feature; it maintains spring tension over extended storage periods so magazines stay reliable without frequent cycling for maintenance.

Why the antifatigue spring matters

Springs lose tension over time—especially in high-stress environments. The antifatigue spring in this magazine is engineered to slow that degradation, offering dependable feed pressure for up to six years of typical storage and use scenarios. That reliability is critical when a spare magazine may be stored for long stretches between uses.

Fit, Function, and Caliber Considerations

Designed specifically for the Springfield XDS, this PROMAG replacement aligns with the platform’s dimensions and feed geometry. Chambered in 45ACP, it supports the caliber’s established benefits: significant energy transfer and proven stopping capability in compact defensive platforms. Whether you’re running drills at the range or carrying for personal defense, having properly functioning 45ACP magazines is essential.
