SIG Sauer P365 9mm Micro Compact, Nitron Slide, Tritium Front Sight, 3.1-Inch Barrel, 10+1 Capacity
The SIG Sauer P365 is a proven micro-compact 9mm with a 3.1-inch barrel and a 10+1 capacity in a slim, easy-to-carry format. This example features a Nitron-finished slide with front and rear serrations, a tritium front sight with a high-visibility green ring, and standard left-side controls. It is the no-manual-safety configuration and comes with its SIG factory case and manual.
The slide is marked P365, and the barrel hood is marked SIG SAUER and 9mm x 19. The frame is marked NEWINGTON, NH USA, reflecting U.S. manufacture. The factory case label is dated 03-MAY-2019, and the pistol corresponds to SIG part number 365-9-BXR3.
This P365 uses a striker-fired action with a curved trigger and a left-side magazine release. The sights are dovetailed, with a tritium front sight (TG-H3) that carries a green ring for quick indexing, paired with a dovetailed rear sight.
The proprietary single-slot P365 accessory rail allows mounting compatible P365-pattern compact lights or lasers. The polymer frame keeps weight low while the Nitron slide finish provides a durable, black protective coating.

What’s Included
- SIG Sauer factory hard case
- SIG Sauer P365 owner's manual
- One 10-round steel magazine with flush floorplate, marked "MADE IN USA"
The P365’s micro size makes it easy to conceal while maintaining a full 10+1 capacity using the included flush-fit steel magazine. Front and rear slide serrations aid in manipulation, and the lack of an external/manual safety delivers a clean, straightforward control layout.
Dovetailed iron sights provide a robust sighting system, with the tritium front (TG-H3) offering low-light capability and a green ring that stands out in brighter conditions. The left-side slide stop, takedown lever, and magazine release mirror SIG’s standard control scheme for the platform.
The proprietary single-slot P365 accessory rail supports P365-specific compact accessories. The Nitron-finished slide and polymer frame present a durable, all-black appearance suitable for regular carry.
U.S. markings include the NEWINGTON, NH USA frame stamp, with clear model and caliber markings on the slide and barrel hood. Documentation includes the factory manual and a case label dated 03-MAY-2019, aligning with SIG’s part number 365-9-BXR3.
