The P365X is part of SIG's XSeries and uses the XSeries grip module with coarse/stippled texture, an extended beavertail, and a slightly flared magwell for confident handling in a micro-sized package. The flat-faced trigger complements the striker-fired action and provides a consistent, straight-back press.
Its Nitron-finished slide includes an optics cut with a Shield RMSc footprint and a rear-sight plate. Dovetailed iron sights are installed, pairing a front blade with a bright green ring and a black, square-notch rear for a clean, high-contrast sight picture.
The 3.1 inch stainless steel barrel and 12+1 capacity deliver micro-compact carry dimensions without giving up on-round count. A SIG micro accessory rail (one slot) is integrated for compatible compact accessories.
This example is built on SIG's modular, serialized fire control unit for straightforward configuration changes within the P365 family. It is configured without a manual safety and is marked as made in the United States. The factory part number is 365X-9-BXR3P-RS.
