CMC Triggers Match Precision 9mm Luger 4.48" Fluted/Threaded Barrel - Glock 17 Gen 3-4 - Bronze DLC

The CMC Triggers Match Precision drop-in barrel is engineered for Glock 17 Gen 3 and Gen 4 pistols chambered in 9mm Luger. Cut from pre-hardened 416R premium grade stainless steel with six rifled grooves at a 1:10 twist, this 4.48" barrel serves as a precision-oriented replacement for factory Glock 17 barrels and is well suited to competition, duty, and range use.

A fluted profile sheds weight while adding surface area for faster heat dissipation, and the barrel is fitted with a SAAMI-spec match grade chamber for tight, consistent headspacing with quality ammunition. The bore and chamber are treated with an hBN (Hexagonal Boron Nitride) coating to reduce friction and fouling, while the exterior wears a durable Bronze DLC (Diamond-Like Carbon) finish that resists corrosion and wear.

The muzzle is machined with 1/2x28 threads for mounting a compensator, suppressor, or thread protector. No sights are installed, leaving the slide free for an aftermarket optic-mounting plate or suppressor-height sight set. The drop-in design installs directly into a factory Glock 17 Gen 3 or Gen 4 slide with no fitting required.
