This P365-380 BSS pairs SIG Sauer's micro-size P365 frame with a .380 ACP chambering and the factory BSS package of a Nitron-finished stainless-steel slide and SIGLITE 3-dot night sights. It features a 3.1 in carbon-steel barrel, a 10+1 capacity, and U.S. production in Newington, NH.

The BSS configuration denotes a Nitron finish over a stainless-steel slide paired with factory SIGLITE night sights. These provide a clear 3-dot night-sight picture.
Built on the micro-size P365 platform, the pistol uses a striker-fired, semi-automatic action and a left-side magazine release. It is configured without a manual safety, aligning with many duty-style striker-fired setups.
The .380-specific design includes a lightened slide and a reduced-rate recoil spring to make slide manipulation easier while helping moderate felt recoil. Deep front and rear slide serrations aid purchase for press checks and administrative handling.
The carbon-steel 3.1 in barrel, polymer grip module with aggressive texture, and the proprietary P365 single-slot accessory rail round out a compact package. Marked for U.S. production in Newington, NH, this example was manufactured in 2022 and carries a 10+1 capacity in .380 ACP.
