The Lantac 9INE Glock G19 Fluted Barrel 416R - Black DLC combines superior 416R stainless steel with Lantacs precision machining to deliver a drop-in, ultra-accurate upgrade for Glock 19 pistols. Crafted from 416R stock known for corrosion resistance, machinability and high tensile strength, this barrel is 6 groove, cut rifled with a 1:10 right-hand twist and finished with a bead-blasted satin surface before the durable Black DLC coating. Each chamber is Match Grade SAAMI spec, precision cut and polished to a smooth, low roughness profile, while the pre-hardened steel is stress-relieved and hardened to 38-42 RC, ensuring exceptional long-term durability. Tight tolerances are held to +/- 0.0002" for consistent accuracy, and the barrel is fully inspected and double honed to produce a pristine bore. The 9INE is a true drop-in fit for Glock 19, requiring no gunsmithing, and features LANTACs patented flute pattern for enhanced rigidity and reduced weight. Available with or without 1/2-28 TPI RH suppressor threads, this fluted barrel elevates performance, reliability, and precision for match-grade shooting and everyday use.
