Micro Optics-Ready SIG Sauer P365X 9mm Luger with RomeoZero Red-Dot, X-Series Flat Trigger
The P365X combines the original P365’s micro-compact size with SIG Sauer’s X-Series upgrades, delivering an optics-ready carry pistol that ships with a factory-installed RomeoZero red-dot sight. A serialized fire-control unit, flat-faced trigger, and extended X-Series grip module make this U.S.-built variant a flexible, performance-oriented option for everyday carry or range use.
Condition
Overall Condition: Very good condition, showing only light, superficial signs of prior handling or use.
Bore Condition: Good – Clean, well-maintained, minor wear marks.
Bore Fouling: Mild Fouling – Light buildup of fouling or dirt.
Bore Rifling: Excellent Rifling – Sharp lands and grooves.
Specific Condition Notes: The pistol exhibits some finish wear consistent with normal use, yet all controls operate smoothly and the slide cycles without issue.
What’s Included
- SIG Sauer RomeoZero 1× micro red-dot sight (factory-installed)
- Four SIG Sauer P365 12-round steel magazines
The P365X is built around SIG’s modular, serialized fire-control unit, letting owners swap grip modules, slides, and barrels without a trip to the armorer. This example wears the XL-length X-Series grip module, giving shooters a full three-finger purchase while maintaining true micro-compact dimensions.
An optics-ready Nitron-finished stainless slide features forward and rear cocking serrations plus a stylised “X” motif. The RomeoZero installs directly to the slide cut, keeping the sight line low and snag-free for concealed carry.
The flat-faced X-Series trigger offers a 90-degree break for a consistent, vertical press. Combined with the striker-fired action and XRAY3 tritium front sight, the package supports rapid, precise shot placement day or night.
True accessory rails allow attachment of compact lights or lasers, and the P365 pattern accepts 12-, 15-, and 17-round magazines for added versatility. Frame markings confirm Newington, New Hampshire manufacture, with prefix “66A-” denoting a recent U.S. production run.
