The Ruger MAX-9 Long Slide Assembly gives you the extended sight radius and longer sight picture that come from a 4-inch barrel without needing to swap out multiple parts. This is a complete replacement slide, meaning it arrives ready to install with the barrel, sights, extractor, and all necessary slide components already assembled. No hunting through parts lists or dealing with incomplete kits.
This assembly is cut and ready for direct-mount micro red dot sights using the JPoint and Shield-pattern footprints, so you can mount optics like the Holosun 407K, Holosun 507K, Shield RMSc, or Crimson Trace CTS-1550 directly to the slide. The optics-ready cut also supports co-witnessing with iron sights, giving you a backup aiming system without adding bulk. If you want to run iron sights alone, the factory-installed sights work with or without a red dot mounted above them.
Moving from the standard 3.2-inch barrel to a 4-inch setup gives you a meaningful boost in sight radius and velocity. The longer sight line makes precision shots easier, whether you're working on accuracy at the range or want a surer sight picture for defensive use. Factory black oxide finish handles the elements, and this genuine Ruger accessory is made in the USA.
Ruger included detailed installation instructions to walk you through the swap. The assembly uses the same recoil spring as the standard MAX-9, so you don't need any additional springs. Installation is straightforward enough that most owners handle it themselves, though you can also bring it to a gunsmith if you prefer. Everything you need to go from your current slide to this one comes in the box.
Yes, this long slide assembly is designed as a direct replacement for the standard MAX-9 slide. It works with the same MAX-9 frame and recoil spring you already have. The swap is straightforward, though make sure you read through the included installation instructions before getting started.
The long slide accepts JPoint and Shield-pattern micro red dot sights using a direct-mount cut. Compatible options include the Holosun 407K, Holosun 507K, Shield RMSc, Crimson Trace CTS-1550, and similar micro dots that fit those footprints. Some other optics may require an adapter plate, so verify your specific sight's compatibility before ordering.
No, the recoil spring is not included. The long slide uses the same recoil spring as the standard MAX-9, so you'll use the spring from your existing pistol. If you don't have one or need a replacement, you'll need to order that separately.
Yes. The slide comes with factory iron sights installed and ready to use. You don't need to mount an optic if you prefer to shoot with iron sights alone. If you add a red dot later, the iron sights can be used as a backup with co-witnessed sighting.
