Description
The Combat Armory CA19 Threaded 9mm is a Gen 3 style compact pistol built on the familiar 19-size footprint, with a 4.49-inch threaded stainless barrel, a slide milled for a red dot, taller fixed sights and a 10-round magazine. It is a budget-minded way into a suppressor-ready, optic-ready pistol.

Combat Armory CA19 Threaded 9mm Overview
Combat Armory builds the CA19 as a value-priced pistol that follows the Gen 3 Glock 19 pattern and adds the upgrades most owners pay for later: a serrated steel slide, an aggressive textured grip, a high undercut trigger guard and a scalloped magazine release area. This configuration, part number CA19PSTHR-RMRTL, is the top of the CA19 line, pairing a threaded barrel with an optic-cut slide and taller sights in a matte black finish. Because it follows the Gen 3 pattern, the frame is designed to accept many OEM and aftermarket Gen 3 parts.
Threaded Barrel and Muzzle Devices
The 4.49-inch stainless steel barrel uses conventional 1:10 rifling and extends past the slide with a threaded muzzle and thread protector. That lets you mount a compensator or a suppressor. Confirm the thread pitch with the factory or your gunsmith before ordering a muzzle device, because pitch is not listed in the distributor data. A suppressor is an NFA item: you need an approved ATF Form 4 and it must be legal in your state. A compensator adds noticeable blast and fouling, so many owners keep the thread protector on for daily carry.

Optic Cut and Sights
The slide carries an RMR cut, so a Trijicon RMR or another optic on the same footprint mounts directly without an adapter plate. The store listing and part number call for suppressor-height sights, which sit high enough to co-witness through many small red dots and to see over the body of a can. The sights are fixed, so plan on a sight pusher if you ever need to adjust windage. The distributor data lists the sights as polymer, which is less durable than steel, so steel replacements are a sensible upgrade for hard use.
Frame, Grip and Controls
The glass-reinforced nylon polymer frame has embedded stainless steel rails, a medium-aggressive texture that grips without shredding a cover garment, a high trigger guard undercut that lets your hand ride higher, and forward landing pads that index your support-hand fingers. The dust cover rail takes the same weapon lights made for Glock 19 frames. The action is striker-fired with a double-action-only style trigger, plus trigger, firing pin and drop safeties. There is no manual thumb safety, so a holster that fully covers the trigger guard is essential.

Magazines and Capacity
This model is listed with a 10-round magazine, which suits states with a 10-round limit. The magazine well follows the Glock 19 pattern and the distributor lists Magpul-type magazines, so Glock 19 pattern magazines such as the PMAG GL9 are the natural spares, and 15-round magazines are an option where your state allows them. Check your state and local capacity rules before buying higher-capacity magazines, and check whether your state requires the pistol itself to appear on an approved handgun roster.
Holsters and Carry
Because the CA19 copies Glock 19 Gen 3 dimensions, most Glock 19 holsters fit, including many light-bearing models. Two caveats apply. The longer threaded barrel sticks out roughly half an inch past a standard Glock 19 muzzle, so the holster needs an open bottom, and the taller sights and any mounted red dot need a holster cut for optics and tall sights. At 7.35 inches overall it is still practical to conceal under a loose shirt or jacket, and it works well as a home defense pistol with a light attached.
State Laws and Ownership
Magazine capacity limits, handgun rosters and assault weapon definitions vary widely by state. Several states treat a threaded barrel on a semi-automatic pistol as a restricted feature, so verify your local law before ordering. We ship firearms only to licensed FFL dealers, and we do not ship to Massachusetts or Oregon. Your receiving dealer will run the required background check and complete the transfer paperwork.

Before You Buy
Federal law requires you to be 21 or older to buy a handgun from a licensed dealer, and the pistol must ship to an FFL for transfer and a background check. Clean and lubricate the pistol before its first range trip, put a few hundred rounds of quality ammunition through it before trusting it for carry, and confirm thread pitch before buying any muzzle device.
Who It Is For
The Combat Armory CA19 Threaded 9mm is a great fit for shooters who want a Glock 19-sized pistol that is already threaded and optic-ready without paying for a custom slide, and for owners planning a suppressor setup once their Form 4 is approved.
