The Ruger SR45 is a capable, no-frills .45 ACP handgun—but its standard magazine capacity might leave you wanting more rounds on hand or spares when your originals wear out. The ProMag RUGA40 13-round magazine for Ruger SR45 fills that gap with a purpose-built steel option that gives you extra firepower and reliability without breaking the bank.
ProMag engineered these magazines around durability. The body is forged from heat-treated steel and finished with a black-oxide coating that stands up to corrosion and daily carry wear. Inside, an injection-molded follower sits atop a magazine spring made from heat-treated chrome-silicone wire—the kind of materials that handle repeated loading and unloading without losing tension or predictability. Built and assembled in the USA, these magazines are sized exclusively for .45 ACP ammunition and the SR45 platform.
Whether you're building a rotation of spares for the range, stocking backup mags for duty carry, or simply want more rounds ready without reloading, the 13-round capacity strikes a balance between loadout depth and practical carry weight. If you've worn out an original SR45 magazine or just want to keep a few fresh ones in the safe, this steel-built option is a straightforward, American-made choice.
