Sig Sauer P320 M17 9mm 4.7 Siglite Romeom17 Blk Slide Assemby 8901632

The SIG Sauer P320‑M17 4.7″ Slide Assembly is a factory‑built, optics‑ready M17 slide finished in black and equipped with SIG’s ROMEO‑M17 reflex sight and SIGLITE iron sights for immediate, low‑deck red‑dot performance. Built from stainless steel and advertised at ≈13.8 oz, the 4.7″ M17 slide accepts standard 4.7″ 9mm P320 barrels and features the SIG‑LOC (M17/M18) optic footprint and a loaded‑chamber indicator for enhanced safety awareness. Sold as a slide assembly (barrel and recoil components are typically not included), it’s an ideal, drop‑in factory option for converting a compatible P320 fire control unit to the M17 configuration without aftermarket fitting.
