Sig Sauer P229 9mm RX 3.9" Slide Assembly with Romeo1Pro

Compatible with Sig 229R & M11-A1 frames only, the Sig SauerA(R) P229 9mm RX 3.9" Slide Assembly with Romeo1Pro optics is a drop-in pistol slide upgrade. Featuring stainless steel construction with a CerakoteA(R) gray finish, this slide offers exceptional strength and consistent performance when and where it matters most. The removable, factory-installed Romeo1Pro red dot sight delivers a crystal clear sight picture and rapid target acquisition, while XRAY3 day and night sights co-witness with the red dot for intuitive target acquisition and dependable performance in any lighting condition. The Romeo1Pro RDS features a CNC-machined aircraft aluminum housing for lightweight strength and durability, while a rugged steel shroud offers additional protection and strength for lasting performance. Simple push-button brightness controls allow you to quickly cycle through 12 brightness settings (10 daylight; 2 night vision) for optimal visibility in any lighting. The molded glass aspheric lenses feature durable LensArmor(TM) coatings for scratch and abrasion resistance. SpectraCoat(TM) performance coatings deliver superior light transmission and eliminate distortion for optimal clarity. The TruHold(TM) Lockless Zeroing System utilizes twin adjustment springs designed to endure punishing recoil and deliver a quick return to zero. MOTAC(TM) (Motion Activated Illumination System) technology automatically powers up the unit when it senses motion and powers down when the weapon is idle for battery conservation. Offering an impressive battery life of up to 20,000 consecutive hours. Note: This slide is compatible with P229R (accessory rail versions) & M11-A1 frames ONLY. If your P229 pistol only works with 13-round 9mm factory magazines, this slide is not compatible.
