Springfield Armory XD OSP 4-Inch 9mm Slide Assembly - Optics Ready Melonite Slide, Co-Witness Iron Sights - Includes Crimson Trace CT1500 Red Dot - Black - XD4903

Product Description

If you own a standard, iron-sighted Springfield XD pistol, upgrading it to use modern red dot optics usually requires a trip to a specialized machine shop for slide milling. This process can keep your defensive handgun away from your bench for weeks and costs a pretty penny. The **Springfield Armory® XD® OSP™ 9mm Slide Assembly (XD4903)** completely cuts out that waiting period. It is a drop-in factory conversion kit that allows you to instantly transform your standard 4-inch 9mm XD into a modern, optics-equipped defensive platform right at your workbench.

This genuine factory upgrade comes directly from Springfield Armory and features a rugged steel slide treated with an ultra-hard, corrosion-resistant black Melonite finish. What makes the Optics Sight Pistol (OSP) configuration special is the precision-machined top cut, which arrives pre-fit with a **Crimson Trace® CT1500 micro red dot sight**. The CT1500 projects a crisp 3 MOA red aiming dot that allows for lightning-fast target acquisition with both eyes open. Additionally, the slide is outfitted with taller, suppressor-height three-dot iron sights, allowing you to seamlessly co-witness through the glass window if your red dot optic ever loses battery power downrange.

The slide assembly arrives completely built out with the factory firing pin assembly, internal extractor, and spring components already installed. To complete the swap on your staging bench, you simply reuse your existing 4-inch 9mm factory barrel and recoil guide rod assembly. It is an ideal, budget-friendly solution for anyone looking to increase their shooting accuracy and transition smoothly to handgun optics without altering their original frame layout.

*Armorer Bench Notes & Real-World Conversion Guidance: The Springfield XD4903 OSP kit arrives securely boxed on your workbench, including 1x Complete Stripped OSP Slide, 1x Crimson Trace CT1500 Red Dot (with protective cover and battery), an optic mounting plate, and necessary assembly screws. CRITICAL HOST FRAME COMPATIBILITY DIRECTIVE: This slide assembly is engineered strictly to fit original full-size Springfield XD 9mm frames with 4-inch barrels. It will not fit XD-M, XD-M Elite, XD-S, XD-E, or Hellcat series pistols due to completely distinct locking block geometries on your bench. Armorer Workbench Conversion Sequence: 1. Ensure your host handgun is completely unloaded, cleared of live ammunition, and safe. 2. Remove your original slide assembly. 3. Take out your factory 4-inch 9mm barrel and dual-spring guide rod from the old slide. 4. Drop your factory barrel and guide rod directly into the new black Melonite OSP slide assembly. 5. Slide the new completed assembly onto your original lower frame structure. Optic Torquing Parameters: If you ever remove the Crimson Trace red dot for deep slide cleaning or battery swaps, make sure to use a drop of light blue threadlocker on the mounting screws and torque them down incrementally to exactly **12 in-lbs**. Over-tightening on your bench can strip the fine threads or damage the internal electronic circuitry downrange.*
