Description
The Combat Armory CA19 takes the most popular compact pistol pattern in the world and adds the one thing a lot of folks end up buying separately anyway: a threaded barrel. The 4.49" stainless steel barrel extends past the slide with threads ready for a suppressor, compensator, or whatever muzzle device you want to run, and the 1:10 twist conventional rifling plays nice with lead, plated, and jacketed bullets alike. Underneath, it feeds from a 15 round magazine for 15+1 on tap, and the serrated matte black steel slide wears fixed polymer sights in the familiar standard height configuration.
A CA19 Frame That Improves on the Original
Combat Armory didn't just copy the Glock 19 frame, they cleaned it up. The glass reinforced nylon polymer frame has embedded stainless steel rails, a medium aggressive grip texture that stays put with sweaty hands, and a high trigger guard undercut that lets you choke up for better recoil control. There's a scalloped magazine release well for quicker mag changes and forward finger landing pads for a consistent support hand index. Small touches, but you feel them on the range.
Gen 3 Parts Compatibility Built Into the CA19
Here's the real kicker: this pistol is made to run Gen 3 OEM and aftermarket parts. That means the massive ecosystem of triggers, connectors, slides, barrels, and internals built for the Gen 3 platform drops right in. It also rides in standard Glock 19 style holsters and accepts the same rail mounted lights and lasers, so you're not hunting for oddball accessories.
Who the CA19 Threaded Model Makes Sense For
If you've been eyeing a suppressor host, want a dedicated range gun you can tinker with, or just like the idea of a proven platform without the name brand price, this configuration checks the boxes. Range reports on the CA19 line consistently mention clean machining, reliable feeding across 115, 124, and 147 grain ammo, and a grip that feels better than expected. It's a workhorse pistol with room to grow as your setup evolves.

Frequently Asked Questions
Is the Combat Armory CA19 compatible with Glock 19 parts and holsters?
Yes, that's one of its biggest selling points. The CA19 is built to accept Gen 3 OEM and aftermarket parts, so triggers, slides, barrels, and internals from the Gen 3 ecosystem drop right in. It also fits standard Glock 19 style holsters and accepts common rail mounted lights and lasers.
Can I mount a suppressor on the CA19's threaded barrel?
That's exactly what it's set up for. The 4.49 inch stainless steel barrel extends past the slide with exposed threading for suppressors, compensators, and other muzzle devices. Combat Armory's 9mm threaded barrels use the common 1/2×28 thread pitch, which covers the vast majority of 9mm suppressors and comps on the market.
What ammo runs well through the Combat Armory CA19?
The barrel uses conventional rifling with a 1:10 twist, which handles lead, plated, and jacketed bullets without issue. Owners report reliable cycling with 115, 124, and 147 grain loads. Like any new pistol, it's smart to test a few boxes of your preferred defensive or match load before relying on it.
Does this CA19 model have an optic cut slide?
No, this configuration comes with a standard serrated steel slide topped with fixed polymer sights at standard height. If you decide to add a red dot down the road, the Gen 3 parts compatibility means optic ready aftermarket slides will swap on easily. Combat Armory also offers separate CA19 variants with an RMR cut from the factory.
