The optics-ready slide uses the Shield RMSc (COMPACT) footprint and includes front and rear serrations, a beveled muzzle, and a barrel-hood witness hole. The rear sight notch is integral to the optics cover plate, while the front sight is SIG XRAY3 day/night with a high-visibility green ring.
The XSeries grip module adds practical control features, including an extended beavertail and a flared magwell. The triangular magazine release is easy to access, and the XSeries flat-faced trigger provides a straight, consistent press. This model has no external manual safety.
Construction is robust and corrosion-resistant: a stainless steel slide with a Nitron finish over a polymer grip module, a stainless steel receiver, and a 3.1 in carbon steel barrel. The serialized modular FCU allows the grip module to be swapped within the P365 family. The frame is marked NEWINGTON, NH USA.
Despite its micro size, the P365X offers 12+1 capacity with the included 12-round magazine and includes the SIG micro accessory rail for compatible add-ons. The overall package is compact, feature-rich, and ready for modern carry configurations.
