If you're running a Glock 17 Gen3 or Gen4 and want to tighten up your accuracy without a gunsmith visit, the CMC Triggers Match Precision Threaded Barrel delivers the kind of precision engineering that separates match-grade performance from stock tolerances. This 4.48-inch 9mm barrel is machined from 416R stainless steel and held to extraordinarily tight specs—five ten-thousandths of an inch—approaching what you'd typically pay a gunsmith to fit. It's a practical upgrade for shooters serious about consistent group sizes at the range or in competition.
The barrel features a six-groove, cut-rifled design with a 1:10-inch twist rate and receives double-honing after rifling to achieve the smoothest bore possible. The Black DLC finish delivers both durability and a clean aesthetic, while the bore and chamber are treated with Hexagonal Boron Nitride for ultra-low friction and reliable performance across high round counts. The threaded design allows you to run a suppressor-ready setup if that's part of your plan.
CMC Triggers built their reputation on trigger work, but they understand that real accuracy gains come from attention to the whole system. This barrel represents that philosophy: tight tolerances, premium materials, and thoughtful finishing rather than marketing hype. It drops into your Gen3 or Gen4 Glock 17 as a drop-in replacement, making it accessible to anyone with basic gunsmith knowledge or a qualified armorer.

Frequently Asked Questions
Will this barrel fit my Glock 17 Gen3 or Gen4?
Yes. This barrel is designed specifically as a drop-in replacement for the Glock 17 Gen3 and Gen4. Note that it is not compatible with Gen5 models.
Can I run a suppressor on this barrel?
Yes. The barrel features a threaded muzzle, making it suppressor-ready. You'll need to verify the thread pitch and pitch adapter compatibility with your specific suppressor.
What's the benefit of the match-grade tolerances?
The tight machining tolerances—held to five ten-thousandths of an inch—reduce vertical stringing and improve shot-to-shot consistency. This is the level of precision you'd normally pay a gunsmith to fit, but CMC delivers it as a drop-in upgrade.
What does the Hexagonal Boron Nitride treatment do?
The HBN treatment applied to the bore and chamber reduces friction, which helps with smooth cycling, easier cleaning, and consistent velocity over extended shooting sessions.
