The P365X MS pairs micro dimensions with a 12+1 capacity using the included 12-round magazines and a 3.1 inch barrel. The textured polymer grip module adds an extended beavertail and slight magwell flare for control and smooth reloads while maintaining a compact footprint.
The stainless steel slide wears a black Nitron finish and carries front and rear cocking serrations. It is optics-ready with an RMSc-pattern micro red dot interface and a factory cover plate. Steel tritium 3-dot night sights come standard, with a green front tritium dot and a two-lamp rear.
Controls are designed for carry-friendly operation: an ambidextrous manual safety, a reversible magazine release, and a flat-faced trigger for a consistent striker-fired pull. The proprietary P365 single-slot accessory rail supports compatible compact lights or accessories.
Built around SIG's modular removable fire control unit, this P365X MS allows grip and slide swaps within the P365 family. It is made in the United States, and this example corresponds to SIG part number 365X-9-BXR3P-MS.
