Product DescriptionUpgrade your SIG Sauer P320 with this feature-packed slide assembly that combines a slide-mounted ROMEO-X Pro reflex sight with SIG's integrated expansion chamber design for a flatter-shooting, faster-returning pistol. The extremely low overall optic height helps deliver a quick sight picture while allowing co-witness with the included standard-height iron sights-eliminating the need for bulky, high-over-bore suppressor-height sights. A Two Port Slide Integrated Expansion Chamber helps mitigate recoil for quicker follow-up shots, and the durable black Nitron-finished stainless steel slide is built for hard use.Product Highlights Slide assembly for SIG Sauer P320 platforms with a factory-installed ROMEO-X Pro reflex sight Two Port Slide Integrated Expansion Chamber helps reduce felt recoil and muzzle rise Low-profile optic setup supports co-witness with included standard-height iron sights Durable stainless steel slide with black Nitron finish and forward cocking serrations Designed for 9mm Luger P320 configurations with a 3.9-inch barrel lengthSpecs Brand: Sig Sauer Manufacturer Part Number: 8901534 UPC: 798681688739 Model Compatibility: P320 Caliber: 9mm Luger Barrel Length Compatibility: 3.9 in Color/Finish: Black (Nitron finish) Material: Stainless steel slide Optic: ROMEO-X Pro reflex sight (slide-mounted) Sights: Included iron sights; co-witness capable (standard height) Recoil Feature: Two Port Slide Integrated Expansion ChamberDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
