SIG Sauer P365 380 ACP Romeo Shield RMS Optic Ready 3.1" 10rd

The SIG Sauer P365 in 380 ACP delivers micro-compact concealed carry performance with optics-ready capability. This variant features the Romeo Shield RMS mounting system, allowing shooters to mount red dot sights on the ultra-compact platform. The 3.1-inch barrel provides optimal velocity for the 380 ACP cartridge while maintaining the P365's renowned concealability.

What Makes This Different

Unlike standard micro-compacts that require aftermarket modifications for optics, this P365 comes factory-equipped with the Romeo Shield RMS optic cut. The 380 ACP chambering offers reduced recoil compared to 9mm variants while maintaining effective stopping power. SIG's proprietary magazine design achieves 10-round capacity in a frame smaller than most single-stack pistols, delivering 67% more ammunition than comparable 380 pocket pistols.

Key Features

• Romeo Shield RMS optic-ready slide with co-witness iron sights

Field performance demonstrates reliable cycling with standard 380 ACP ammunition from 90 to 102 grains. The optic-ready configuration accepts popular micro red dots including Romeo Zero, Holosun 407K, and RMSc footprint sights. Weather sealing protects internal components during adverse conditions, while the Nitron coating resists corrosion and wear. Accuracy testing shows 2.5-inch groups at 15 yards with quality ammunition.
