SIG Sauer P365 Nitron Micro-Compact 9mm Luger, Striker-Fired, 10+1-Round Capacity
The SIG Sauer P365 set the standard for high-capacity micro-compacts when it debuted in 2018, and this early-production example delivers that benchmark performance in a lightweight, easily concealed package. Its modular serialized fire-control unit allows caliber or grip swaps without new paperwork, while factory XRAY3 night sights and a matte black Nitron slide give the pistol duty-grade features in a pocket-sized form.
Condition
Overall Condition: Excellent – showing only faint signs of prior use or handling.
Bore Condition: Excellent – clean, mirror finish, sharp lands and grooves.
Specific Condition Notes: Minimal handling marks are present but do not affect function or appearance.
What’s Included
- SIG Sauer grey plastic hard case
- Two 10-round SIG Sauer factory steel magazines (one flush, one with finger-extension baseplate)
This P365 retains the compact 3.1-inch carbon-steel barrel and double-stack magazine that give the model its 10+1-round capacity while maintaining a micro footprint. The striker-fired action uses a smooth-faced curved trigger for consistent pull and short reset.
The slide wears SIG’s durable matte black Nitron finish and features both front and rear serrations for confident manipulation. A proprietary two-slot SIG accessory rail sits ahead of the trigger guard, ready for compact lights or lasers.
Factory-installed XRAY3 three-dot tritium sights offer a green-outlined front and a square-notch rear, providing fast target acquisition in daylight and low light alike. Combined with the pistol’s narrow profile and mild recoil, they make rapid, accurate shots straightforward.
An early production date of 30-NOV-2018 aligns with the launch period of the P365 line, adding collector interest for buyers who value first-run examples. The modular serialized fire-control unit further enhances long-term versatility, allowing the user to adapt frames or even calibers as SIG expands the P365 ecosystem.
