ProMag SPR10 8-Round Extended Magazine .45 ACP Springfield XDS

The ProMag SPR10 extends Springfield XDS capacity from 5 to 8 rounds of .45 ACP, providing 60% more firepower in a compact platform. This extended magazine maintains the XDS's concealability while delivering the stopping power advantage that .45 ACP shooters demand.

What Makes This Different

Unlike flush-fit factory magazines, the SPR10 adds minimal length while maximizing capacity. The blued steel construction resists corrosion better than polymer alternatives and withstands repeated loading cycles without feed lip deformation. Heat-treated spring steel maintains consistent tension through thousands of loading cycles, ensuring reliable feeding even when magazines sit loaded for extended periods.

Key Features

• 8-round capacity increases firepower by 60% over standard 5-round magazines
• Blued steel body construction for enhanced durability and corrosion resistance
• Heat-treated spring maintains consistent tension and reliable feeding
• Extended baseplate provides improved grip purchase during reloads
• Drop-free design ensures positive ejection during tactical reloads
• Compatible with all Springfield XDS .45 ACP models
• Witness holes allow quick visual ammunition count verification

Field testing demonstrates consistent feeding with various .45 ACP loads, from 185-grain target rounds to 230-grain defensive ammunition. The extended length adds approximately 0.75 inches to overall grip length while maintaining reliable concealment under most cover garments. Competition shooters appreciate the reduced reload frequency during extended strings of fire, while concealed carriers value the additional capacity without significant size penalty.
