Sig Sauer P320 .45ACP W/Box
Sig SauerDiscover the Sig Sauer P320 in .45 ACP: a versatile, modular striker-fired pistol that delivers legendary stopping power in a customizable package. As part of the acclaimed P320 series—trusted by military and law enforcement worldwide, including the U.S. Army's M17/M18 variants—this .45 ACP model combines robust construction with innovative design, making it perfect for duty, home defense, or range use.
Built around Sig Sauer's revolutionary serialized fire control unit (FCU), the P320 allows seamless swaps of grip modules, slides, barrels, and even calibers, adapting to your needs without tools. Its durable stainless steel slide with nitron finish resists corrosion, while the ergonomic polymer grip module (available in small, medium, or large sizes) ensures a comfortable, secure hold with textured surfaces and an accessory rail for lights or lasers. The full-size configuration features a 4.7-inch hammer-forged barrel for superior accuracy, measuring 8.0 inches overall and weighing just 30 ounces unloaded—balancing heft for recoil management with portability.
Chambered in the hard-hitting .45 ACP, it holds 10+1 rounds in double-stack steel magazines, with options for extended capacities. SIGLITE night sights provide quick target acquisition in any light, and optics-ready models support popular red dots like the ROMEO series for enhanced precision. The crisp trigger pull (around 5.5-6.5 lbs) with short reset promotes fast, accurate follow-ups, while internal safeties—including striker and disconnect mechanisms—prioritize reliability. For added peace of mind, Sig offers voluntary upgrade programs to enhance drop safety based on extensive testing.
Proven in rigorous field use, the P320 .45 ACP excels with controllable recoil, exceptional durability, and flawless feeding of various ammo types, from ball to hollow points.
