SIG Sauer P365 Nitron 9mm, 12+1, Night-Sight, Striker-Fired Pistol
The SIG Sauer P365 Nitron is the pistol that redefined capacity in the class. Released in 2018, it delivers a 12-round magazine in a frame small enough for discreet carry, yet rugged enough for duty use. Its modular stainless-steel fire-control unit, SIG XRAY3 tritium night sights, and +P rating make this USA-made striker-fired sidearm a practical, feature-rich option for everyday carry or collection.

This P365 carries a matte black Nitron-finished stainless slide with front and rear cocking serrations for confident manipulation in any condition. The carbon-steel barrel is nitride treated for durability and corrosion resistance, measuring 3.1 inches to balance concealability with reliable velocity.
SIG XRAY3 three-dot tritium night sights provide a bright green front dot flanked by two rear tritium dots, ensuring rapid sight acquisition day or night. Minor scuffs near the sight bases reflect normal holster wear without affecting function.
The serialized stainless-steel fire-control unit is the heart of the P365’s modularity, allowing the user to swap grip modules for size or color preferences. A proprietary single-slot SIG accessory rail accepts compact lights or lasers without enlarging the profile.
The reversible magazine release supports left- or right-handed shooters, and the striker-fired action delivers a consistent trigger pull. Rated for +P ammunition, the pistol offers added performance headroom while maintaining controllability in the format that inspired many later designs.
