Will a Gen 5 barrel fit a Gen 4 Glock 19?

No. Gen 5 barrels have a different locking lug design and must be used only with Gen 5-compatible Glock models like the G19 Gen 5, G45, and G19X.

What thread pitch do your Glock 19 Gen 5 barrels use?

All threaded barrels for Glock 19 Gen 5 use the standard 1/2x28 thread pitch, compatible with most 9mm suppressors and muzzle devices.

Which finish is most durable?

DLC and Black Nitride finishes are among the most durable. TiN is also highly wear-resistant and provides a distinctive gold color.

Are these barrels drop-in fit?

Yes. All Glock 19 Gen 5 barrels listed are precision-machined for drop-in fitment with no gunsmithing required.

Glock 19 Gen 5 Barrel – Match-Grade Upgrades Without the Gunsmith

Looking to enhance your Glock 19 Gen 5’s performance, recoil control, or suppressor compatibility? Whether you're refining your carry pistol or building a custom rig, a precision-crafted barrel is a fast, drop-in upgrade that makes an immediate impact.

At Mounts Plus, we carry a curated selection of premium, Gen 5-compatible pistol barrels from leading brands like Faxon, Zaffiri Precision, Grey Ghost, and Fortis. Threaded or flush-fit, black nitride or TiN gold — there’s an option built to match your build style, shooting preference, and aesthetic goals.

🔧 Why Upgrade Your Factory Barrel?

OEM barrels are reliable — but they’re made for mass production, not peak performance. Swapping in a match-grade alternative can deliver:

Tighter groups at distance
Improved performance with suppressors and comps
Enhanced durability from high-end finishes
Stylish upgrades that make your Glock your own

Whether you're running a red dot or just want more consistency at the range, upgrading your barrel is one of the most effective changes you can make.

🧩 Built for Gen 5 Compatibility

Not all Glock parts are created equal — and Gen 5 models have a unique locking lug design. That means they require barrels built specifically for Gen 5 Glocks like:

Glock 19 Gen 5
Glock G45
Glock G19X

Every barrel we offer on this page is engineered to fit Gen 5 frames with no fitting required.
