Shadow Systems brought back their replacement Gen 3 slides for the G19 compact, and this one comes fully assembled with everything you need except a barrel and recoil spring. It's built from billet 17-4 stainless steel and finished in matte nitride for wear resistance and corrosion protection you can count on.
The patented Shadow Systems optic cut is the standout feature here. Instead of those tiny adapter plates and screws that come loose, this cut lets you mount most modern red dot optics directly to the slide at an ultra-low height. Whether you're running an Eotech, Holosun, or Trijicon, it works without any plates or extra hardware. The front and rear angled serrations give you solid purchase when manipulating the slide, and the window cuts help keep weight down without sacrificing rigidity.
You get a fully assembled slide with Shadow Systems internals, including a round-tip firing pin, high-reliability 9mm extractor, firing pin safety, and all the springs and components you'd need. Factory tritium night sights come standard, with a green front sight and black rear sight. The black flat aluminum cover plate is included too. Just add a Gen 3 Glock barrel and recoil spring assembly and you're in business.
This slide is designed specifically for Glock Gen 3 compact frames or other compatible platforms like P80s. The overall length comes in at 7.13 inches and it weighs 0.8 pounds. Keep in mind it's not compatible with Shadow Systems proprietary frames, and you'll need a standard Gen 3 recoil assembly to complete the build.
Yes, this slide is designed to work with standard Glock Gen 3 compact frames and compatible frames like P80s. Keep in mind that it does not fit Shadow Systems proprietary frames (MR/DR/XR/CR920). You'll need a Gen 3 Glock barrel and recoil spring assembly to complete the build.
The patented Shadow Systems optic cut accepts most major red dot optics directly to the slide without adapters or plates. This includes popular brands like Eotech, Holosun, Trijicon, and others. The design allows for ultra-low optic mounting compared to standard adapter plates.
No, this is a complete slide assembly without a barrel or recoil spring assembly. You'll need to source a compatible Gen 3 Glock barrel or Shadow Systems MR/XR920 barrel separately to complete your build. The recoil spring assembly is also sold separately.
No. This slide comes with a round-tip Shadow Systems firing pin and you must use Shadow Systems round-tip firing pins only. Conventional rectangular-tip firing pins will damage the slide and void the warranty.
