Sig Sauer P365X Slide Assembly 9mm 3.1" Optics Ready Black Nitride

The Sig Sauer P365X slide assembly transforms standard P365 pistols into optics-ready platforms without requiring a complete firearm purchase. This factory slide features a precision-machined optics cut compatible with popular micro red dot sights, paired with XRAY3 day/night sights for backup aiming capability.

What Makes This Different

Unlike aftermarket slide modifications that can void warranties, this OEM slide assembly maintains factory tolerances and reliability standards. The integrated optics cut eliminates the need for adapter plates on most micro red dots, creating a lower profile mount. Black nitride coating provides superior corrosion resistance compared to standard Melonite finishes, extending service life in harsh environments.

Key Features

• Factory optics cut compatible with Shield RMSc, Romeo Zero, and similar micro red dot footprints
• XRAY3 day/night sights with tritium inserts for 24-hour visibility
• Black nitride finish rated for 50,000+ round service life
• 3.1-inch barrel length optimized for concealed carry applications
• Direct replacement for P365 slides with no fitting required
• Machined from 17-4 stainless steel billet construction
• Compatible with standard P365 holsters and accessories

Field testing demonstrates consistent accuracy with factory ammunition, maintaining 2.5-inch groups at 25 yards with quality defensive loads. The optics cut accepts red dots without compromising structural integrity, while the XRAY3 sights provide reliable backup if electronics fail. Weather sealing around the optics mount prevents moisture intrusion during extended outdoor use.
