Sig Sauer P365 Nitron Micro-Compact 9mm Striker-Fired Pistol – 12+1 Capacity, X-RAY3 Tritium Sights
Sig Sauer’s P365 Nitron Micro-Compact rewrote the rules for concealed carry by fitting a double-stack 10-plus-round magazine into a pistol just one inch wide. Its modular stainless steel fire-control unit, safe takedown system, and +P rating give buyers a modern, high-performance sidearm that remains exceptionally easy to carry. This very good-condition example includes both 10- and 12-round factory magazines and the bright X-RAY3 tritium sight system that helped make the P365 America’s top-selling handgun soon after launch.

What’s Included
- SIG Sauer factory grey hard case

The P365’s serialized stainless steel fire-control unit allows grip module and caliber swaps without an FFL transfer, giving owners unusual flexibility for future upgrades.
A Nitron-finished stainless slide with front and rear cocking serrations pairs with a carbon steel 3.1-inch barrel, providing corrosion resistance and durability in a pistol that remains only 17.8 oz unloaded.
SIG’s X-RAY3 tritium sights place a high-visibility green front ring between drift-adjustable rear dots, delivering fast daylight acquisition and clear low-light aiming without need for batteries.
The narrow-neck double-stack magazine design grants 10 + 1 or 12 + 1 capacity—performance that previously required a larger frame—while the aggressively textured polymer grip offers secure 360° purchase.
A striker-fired action with curved trigger, safe takedown lever that requires no trigger pull, and +P ammunition rating round out a carry gun widely adopted by plain-clothes law-enforcement units.
