As part of the P365 series, the P365-380 is a micro-size striker-fired pistol chambered in .380 ACP with a 10+1 capacity. The slide is marked P365, and the barrel hood is marked SIG SAUER .380 ACP. This variant was introduced in 2022 to offer easier slide manipulation and reduced recoil in the trusted P365 footprint.
The 3.1 in carbon steel barrel pairs with a Nitron-finished slide that carries front and rear cocking serrations for confident handling. The slide is optics cut and includes the factory cover plate, while the dovetailed 3-dot iron sights provide a straightforward sight picture.
The polymer grip module uses micro-texture on the sides and frontstrap for purchase without bulk. A left-side, push-button magazine release and a single-slot accessory rail on the dustcover add functional touches without increasing size.
The locked-breech, short-recoil action keeps the package slim and carry-friendly while maintaining reliability. Being part of SIG’s modular P365 ecosystem with a removable fire control unit and grip module further enhances serviceability and future flexibility.
