Calculated at Checkout
Norton Shopping Guarantee


The Shadow Slide is the premier hard-use, no-fail option on the market today. From forward serrations to make weapon manipulation, to a reducing glare on a bright day with top-side striations, the Shadow is the ultimate slide in function and form. If you're running a gun hard, where failure is not an option and you need every feature you can get, trust your Shadow.

Key Features: 

Forward Serrations for more effective manipulation & press-checks, no matter how sweaty, wet, or dirty the gun gets. 

RMR Cut w/ Cover Plate  allows for mounting the most popular optics platforms, but gives you the option to stick to traditional sights.

Beveled Edges Faster in and out of the holster with less snagging.

If you choose a Slide Completion Kit with a barrel and guide rod option you'll receive one of our match-grade G19 barrels. These are its specs:

Rifling Twist: 1:10"
Rifling Typet: Cut Rifling
Finish: Salt Bath Nitride
Steel: 416R  
Barrel Crown: 45* Chamfer

The Shadow ships bare & stripped (no sights) as standard, or you can order it completed with a Slide Completion Kit that we'll install for you, as well as the  front dot sight with blacked out rear sights.

*Please note that a slide completion kits refers to the slide's internal parts such as the striker assembly, firing pin safety, extractor and backplate. It does not refer to the guide rod and recoil spring or barrel.
