The Sig Sauer P365-380 (MFG# 365-380-BSS-MS) is a micro-compact, optic-ready pistol chambered in .380 ACP that pairs a slim grip module with a 10-round magazine capacity. It ships with SIGLITE night sights, a manual thumb safety, and two 10‑round steel magazines. The slide is Nitron finished stainless steel with an optic cut compatible with SIG RomeoZero-style footprints.

For a reflex optic under $1000 that pairs well with the P365-380, consider the SIG RomeoZero (ROMEOZero Elite footprint compatibility is stated for this slide). The RomeoZero offers a compact footprint and co-witness options that suit the pistol’s size and sight radius.
