Upgrades & Parts to Customize Your Glock

The parts you need to build and enhance

Make It Yours

Whether you’re building or upgrading, we have everything you need to customize your Glock.

Shadow Systems offers custom parts and accessories to fit Glock pistols. Use Shadow Systems parts to complete a pistol upgrade to your existing Glock or pair Shadow Systems parts with your 80% frame to finish your home build. Whether you’re upgrading your Glock, or building your P80 from the ground up, we have parts that can help you create the perfect custom handgun. We also carry bundles including our Polymer 80 Glock kit that make building your gun simple. The engineering behind our custom parts and accessories comes from our team’s history as combat veterans, law enforcement officers, and competitive shooters. We’ve created the parts and upgrades that we always wanted for our guns, whether for duty or daily carry, and everything in between. Be sure to shop our custom slides or threaded barrels to fit Glock pistols!


We offer Shadow Systems-made barrel upgrades to fit your Glock G17 and G19. Our 416R Stainless Steel match-grade barrels come in Bronze TiCN (Titanium CarboNitride) and Black DLC finishes. We machine flutes in our barrels as a standard option.

Every slide that we build features aggressively raked serrations to provide firm gripping surface when manipulating the weapon at high speed. Our slides typically have slightly tighter tolerances than Glock stock slides.

The Shadow Systems Elite Trigger was designed to incorporate the best characteristics of a premium flat-faced trigger in a no-nonsense design that is ready for daily carry and hard-use duty. This trigger will improve the shootability of the gun under stress without sacrificing safety and common sense.

Shadow Systems internals are built to specifications that equal or exceed OEM components. For example, our firing pins, depressor plungers, and firing pin safeties are cut from solid 17-4 stainless steel, not MIM’d.

Upgrade your existing Glock frame and improve your handling with a Shadow Systems grip job. All of our grip work is carefully done by hand and perfectly blended. This makes it substantially more consistent and visually appealing than other grip work in the market.
