Threaded drop-in 9mm barrel for Glock 26 pistols, Gen 1 through Gen 5. Replaces the factory barrel with no fitting or gunsmith work. 1/2x28 muzzle threading lets you run a compensator, suppressor, or thread protector on a sub-compact platform. Built from 416R stainless steel with a hard-coat black nitride finish that runs barrel-length including the chamber. The nitride process produces a slick, corrosion-resistant surface that holds up to holster wear, weather, and high round counts. The 1:16 twist stabilizes standard 9mm projectile weights from 115gr through 147gr. Fits Glock 26 Gen 1-5 9mm Luger, 1:16 twist 416R stainless steel construction Hard-coat black nitride finish 1/2x28 muzzle threading Drop-in replacement - no fitting required Compatible with standard 1/2x28 9mm comps and suppressors Lube the slide rails and barrel hood on the first install. Tolerances can be snug on a new barrel - a short break-in run of 50 to 100 rounds seats the fit and smooths cycling. Verify your suppressor or compensator is rated for 1/2x28 9mm before threading. See our slide break-in guide for the full procedure. DISCLAIMER: "GLOCK" is a federally registered trademark of GLOCK, Inc. and is one of many trademarks owned by GLOCK, Inc. and GLOCK Ges.m.b.H.
