Sig Sauer P365X 9mm | 3.1″ Barrel | 365X-9-BXR3P

The Sig Sauer P365X is a sub-compact, optics-ready 9mm pistol built around the XSeries grip module and a 3.1-inch barrel. It ships with X-Ray3 day/night sights and two 12-round magazines, making it a high-capacity option in a concealable package. For a compact red-dot that pairs well with this platform, consider the SIG Sauer ROMEOZero, which is compatible with the P365X footprint and falls well under a $1,000 price point. Typical applications for the P365X include everyday concealed carry and concealed-carry competition where compact size and quick sight acquisition are priorities.
