Sig Sauer P365X 9mm 10+1 3.1" Optic Ready Black Nitron Slide

The Sig Sauer P365X delivers enhanced capacity and improved ergonomics in a compact carry platform. This optic-ready variant features a 3.1-inch barrel with extended grip module, providing better control and increased magazine capacity over standard micro-compact pistols.

What Makes This Different

The P365X bridges the gap between micro-compact and compact pistols with its extended grip frame that accommodates 12-round magazines while maintaining a 1-inch slide width. The optic-ready slide accepts popular micro red dot sights without requiring adapter plates. Sig's proprietary Nitron finish provides superior corrosion resistance compared to standard Melonite coatings, with documented salt spray testing exceeding 120 hours.

Key Features

• Optic-ready slide cut compatible with ROMEOZero, DeltaPoint Pro, and similar micro optics
• Extended grip module increases capacity to 12+1 with flush-fit magazines
• 3.1-inch stainless steel barrel with black Nitron finish for corrosion resistance
• Serrated slide provides enhanced grip for press checks and malfunction clearing
• Integrated beavertail reduces felt recoil and prevents slide bite
• Compatible with standard P365 holsters and accessories
• Night sights with SIGLITE tritium inserts for low-light visibility

Field testing demonstrates consistent 2.5-inch groups at 25 yards with quality ammunition. The extended grip frame reduces muzzle flip compared to standard P365 models, enabling faster follow-up shots during rapid fire strings. Law enforcement agencies report reliable function through 5,000+ round test protocols without parts replacement. The pistol functions reliably in temperature ranges from -20°F to 140°F with various ammunition weights.
