The CMC Triggers Match Precision Threaded Barrel for Glock 19 Gen3-4 is a precision 9mm barrel engineered for shooters who want to tighten up their handgun's accuracy without a gunsmith visit. Built from 416R stainless steel and finished in a satin DLC coating, this 4.01-inch barrel is machined to extraordinarily tight tolerances—about as close as you can get in a factory-style Glock barrel. If you're running a Gen 3 or Gen 4 Glock 19 and looking to improve shot-to-shot consistency at the range or in competition, this is the kind of upgrade that actually moves the needle.
CMC Triggers didn't stop at tight machining. The bore is double-honed after rifling to deliver the smoothest possible feed and extraction, and tolerances are held to five ten-thousandths of an inch—a level of precision you'd normally expect from a custom gunsmith barrel. The six-groove cut-rifled design with a 1:10-inch twist is optimized for 9mm performance. All of that precision is further enhanced by an ultra-low friction Hexagonal Boron Nitride treatment applied to the bore and chamber, reducing drag and friction for cleaner rounds downrange.
The satin DLC finish strikes a balance between corrosion resistance and a professional appearance—darker than polished stainless but not as aggressive as a full-black nitride coat. The threaded design means you can run a compensator or suppressor if your setup calls for it. Whether you're fine-tuning a match pistol, building a suppressor host, or simply chasing tighter groups, this barrel delivers the kind of precision that makes a real difference in a precision handgun.
| Caliber | 9mm |
| Barrel Length | 4.01 inches |
| Material | 416R Stainless Steel |
| Finish | Satin DLC (Bead Blasted) |
| Rifling | Six-groove, cut-rifled |
| Twist Rate | 1:10 inch |
| Thread Type | Threaded |
| Compatibility | Glock 19 Gen 3, Gen 4 |
| Tolerance | ±0.0005 inch |
Yes. This barrel is specifically designed for Glock 19 Gen 3 and Gen 4 models. It is not compatible with Gen 5 or other Glock platforms.
The barrel is threaded, so it is compatible with threaded 9mm accessories such as suppressors and compensators, provided they are rated for 4.01-inch barrels.
The barrel is machined to extraordinarily tight tolerances (five ten-thousandths of an inch), features a double-honed bore for smooth performance, and includes a Hexagonal Boron Nitride treatment in the bore and chamber to reduce friction. These features combine to improve shot-to-shot consistency compared to standard Glock barrels.
The satin DLC (Diamond-Like Carbon) finish on this model provides excellent corrosion resistance and a professional matte appearance. CMC Triggers also offers this barrel in all-stainless Satin Black and Bronze TiCN finishes, all of which include the same bore treatment.
