If you're running a Glock 19 Gen3 or Gen4 and want to tighten up your accuracy game, a CMC Triggers Match Precision Threaded Barrel for Glock 19 Gen3-4 delivers the kind of precision engineering that makes a real difference on the range. CMC has built a reputation upgrading Glock internals, and this match-grade barrel brings that same commitment to tolerances and fit. The 4.01-inch barrel is machined from 416R stainless steel held to extraordinarily tight specs—we're talking five ten-thousandths of an inch—which puts it in the realm of gunsmith-quality work without the gunsmith price tag.
The barrel features a traditional six-groove rifled design with a 1:10-inch twist optimized for 9mm performance. After rifling, CMC double-hones the bore to achieve that ultra-smooth surface that reduces friction and can improve both accuracy and shot-to-shot consistency. The Black DLC finish looks sharp and offers durability, while a Hexagonal Boron Nitride treatment in both bore and chamber keeps friction to a minimum during firing and cleaning. The threaded muzzle opens up suppressor options or allows you to run a compensator if your platform supports it.
Whether you're building a precision 9mm for competition, hand-loading to match-grade specifications, or simply want a tighter barrel than factory Glock offerings, this CMC barrel is a serious upgrade. It's a drop-in fit for Gen3 and Gen4 Glock 19 frames—no fitting or gunsmithing required—making it an accessible way to improve accuracy and reliability.
