Stoeger STR-45 .45 ACP 4.5" Barrel 13+1 Black 31798

Stoeger STR-45

The Stoeger STR-45 is a full-size polymer-frame striker-fired pistol chambered in .45 ACP, representing Stoeger’s first full-sized handgun in this hard-hitting caliber. It features a 4.5-inch barrel, nitride-hardened matte black slide, tritium night sights, optic-ready slide cut, and an accessory rail, delivering modern ergonomics, enhanced capacity, and reliable defensive performance.

The optics-ready slide accepts popular micro red dot footprints for rapid target acquisition while preserving co-witness capability with the tritium night sights. Interchangeable backstraps in medium and large sizes allow a custom grip fit that improves control and recoil management with the .45 ACP cartridge. A 13+1 capacity provides more rounds between reloads than traditional single-stack .45 pistols, and the tactile loaded chamber indicator offers an immediate visual and physical safety cue. The frame texture, beavertail geometry, and overall mass distribution promote manageable recoil and consistent follow-up shots.

The STR-45 excels for duty use, home defense, and range work where full-power .45 ACP terminal performance is desired alongside contemporary features such as red dot compatibility and accessory mounting. Its full-size frame, balanced handling, and user-configurable ergonomics make it a practical choice for shooters seeking a modern large-caliber pistol with increased capacity, reliability, and adaptability in a straightforward, value-driven package.
