This P365 X-Full configuration uses a stainless steel slide finished in Nitron and a 4.3 in carbon-steel barrel with a DLC finish. The long-slide format and extended sight radius (approx. 6.0 in) contribute to a sight picture that is easy to track with the green fiber-optic front and serrated black rear notch.
The slide is cut for micro optics using the RMSc footprint and includes front and rear serrations, relief cuts, and an external extractor. The design keeps the top end trim while providing aggressive manipulation surfaces.
The XSeries LXG grip module adds laser-engraved texturing and supports interchangeable backstraps, plus a removable flared magwell for fast magazine seating. A full-length M1913/Picatinny rail on the dust cover accommodates compatible accessories.
Controls and internals are striker-fired with a flat-faced, nickel-plated X-Series trigger for a consistent pull. Capacity is 17+1 with the included steel P365-series magazine.
Factory labeling identifies the model code 365XF-9-BFO-RXX and confirms U.S. manufacture.
