Fits Glock 19 9MM Ported Barrel Threaded IN Radio Active

About this product

This is a Combat Armory ported, threaded aftermarket barrel built to drop into a Glock 19, finished in the brand's eye-catching "Radio Active" color. Like all Combat Armory Glock 19 barrels, it's an aftermarket replacement part rather than a Glock OEM component, designed to bolt in without fitting on compatible Gen 1 through Gen 5 frames.

What does a ported barrel do, and what do you need to use it?

Porting cuts vents into the top of the barrel near the muzzle, bleeding propellant gas upward to help counteract muzzle rise during recoil — similar in concept to a ported slide or compensator, but built into the barrel itself. Because the ports need somewhere to vent through, this barrel requires a slide that's also cut with matching ports; installing a ported barrel in a non-ported (solid-top) slide will trap gas instead of venting it, so confirm your slide is ported, or plan to pair this barrel with a ported slide, before ordering.

What are the exact specs?

The barrel is machined from 416 stainless steel, heat treated to Rc 41, with a fully supported chamber and an improved feed ramp for reliable feeding across lead, plated, and jacketed bullets. It measures 4.462 inches in length — matching the factory Glock 19 barrel — with a 1:10 twist rate and a 1/2x28 threaded muzzle for a compensator, thread protector, or suppressor once the porting function isn't needed for a given range session. The Radio Active finish is a distinct, brightly-toned PVD coating that stands out clearly against a standard black slide.

Combat Armory also offers this same ported barrel design in other finishes, including gold, so if the Radio Active color isn't the look you're after, the underlying spec and fit are shared across the line.

Who should buy a ported, threaded Glock 19 barrel?

This is the right part for Glock 19 owners who already have, or plan to install, a ported slide and want a matching ported barrel to complete a recoil-reducing setup for competition or range use. It's not the right choice if your slide is solid (non-ported), since the barrel's ports need a path to vent through the slide to do anything useful. If your slide isn't ported, Combat Armory's non-ported match-grade barrels are the better fit.

As an aftermarket part rather than a complete firearm, this barrel ships directly to the address on your order — no FFL transfer is required to buy a standalone replacement barrel for a pistol you already own.

Before ordering, it's worth double-checking your slide's porting pattern against the barrel's port locations if you're buying both pieces separately rather than as a matched set, since misaligned porting between a barrel and slide can reduce the intended muzzle-rise benefit even when both parts are individually ported. If you already run a Combat Armory ported slide, the two are designed to work together without any additional fitting. Beyond the recoil-control benefit, the ported design also gives the pistol a distinct look and sound signature at the range compared to a solid-top slide and barrel, which is part of why porting has stayed popular among competition and range shooters even as opinions on its practical recoil benefit vary. As with the brand's other Glock 19 barrels, the 4.462-inch overall length matches the factory specification, so your existing holster should continue to fit without modification once the new barrel and matching slide are installed.
