CMC Triggers
If you're running a Glock 17 Gen3 or Gen4 and want measurably tighter shot grouping, the CMC Triggers Match Precision Barrel is built for shooters who won't settle for factory tolerances. This 4.48" bronze DLC-finished barrel is machined from 416R stainless steel to extraordinarily tight specs—tolerances held to five ten-thousandths of an inch—making it as dialed-in as you can get without a gunsmith-fit custom barrel. Whether you're fine-tuning a carry gun or building a competition rig, tighter tolerances mean better consistency where it counts: at the target.
The barrel features a traditional six-groove rifling pattern with a 1:10-inch twist optimized for 9mm Luger. After rifling, CMC double-hones the bore to maximize smoothness and minimize friction. The fluted design reduces weight without sacrificing strength, and the threaded muzzle opens options for suppressors or compensators. The bronze DLC coating protects against corrosion while delivering the aesthetic appeal of precision parts; internally, a Hexagonal Boron Nitride treatment in the bore and chamber further reduces friction and wear.
Drop-in replacement for Gen3 and Gen4 Glock 17 platforms—no gunsmithing required. This is the barrel for shooters who want factory-reliable function paired with match-grade precision.
| Barrel Length | 4.48" |
| Caliber | 9mm Luger |
| Compatibility | Glock 17 Gen3, Gen4 |
| Material | 416R Stainless Steel |
| Finish | Bronze DLC |
| Rifling | Six-groove, 1:10-inch twist |
| Muzzle | Threaded |
| Bore Treatment | Hexagonal Boron Nitride (HBN) |
| Tolerance | Five ten-thousandths of an inch |
Yes. The CMC Match Precision Barrel is a drop-in replacement for Glock 17 Gen3 and Gen4 models. No fitting or gunsmithing is required.
The primary difference is tolerance. CMC machines this barrel to five ten-thousandths-inch tolerances and double-hones the bore for smoothness—tighter and more consistent than factory specifications. The result is reduced shot-to-shot variation and better accuracy, especially at distance or in precision shooting disciplines.
Yes. The barrel is threaded at the muzzle, allowing you to mount suppressors, compensators, or other muzzle devices with appropriate threading.
HBN is an ultra-low friction coating applied to the bore and chamber. It reduces friction, heat, and wear during firing, contributing to smoother operation and extended barrel life.
