The XSeries configuration combines the compact 3.1 in barrel and slide with the XL-length grip module for 12-round magazine compatibility while keeping the overall footprint streamlined. The stippled polymer grip with an extended beavertail provides secure purchase and consistent hand placement.
Steel SIG X-RAY3 day/night sights deliver a bright green front dot and a tritium 2-dot square-notch rear, with a 4.9 in sight radius for clear indexing. Front and rear slide serrations aid manipulation from multiple positions.
A stainless-steel receiver (FCU) sits inside the polymer grip module, paired with a steel barrel and a black Nitron–finished slide for durability. A proprietary single-slot accessory rail is integrated into the frame for compact light or accessory fitment.
The striker-fired action uses a flat-faced trigger. There is no external manual safety. Factory markings include a slide marked P365 with a stylized X and a barrel marked SIG SAUER and 9mm x 19. The magazines are steel and made in the United States.
