Glock 26 fluted 9mm barrel - drop-in replacement for Gen 3 and Gen 4 subcompact frames. Built to OEM-spec chamber and lug geometry so it seats directly into a factory Glock 26 slide - no fitting, no gunsmithing, no hand-lapping before you head out to shoot. Finished in black nitride over 416R stainless for corrosion resistance and surface hardness. Pocketed fluting on the OD trims weight off the reciprocating mass and opens surface area for faster heat dissipation during sustained range strings, which keeps chamber temps in check during carry-class drills. Specs: Caliber: 9x19mm Luger Fit: Glock 26 Gen 3 and Gen 4 (not Gen 5) Material: 416R stainless, black nitride finish Pocketed fluting - lighter, faster cooling OEM chamber and lug geometry Non-threaded crown muzzle Gen 5 fit note: Gen 5 G26 uses a different barrel geometry and will not accept this barrel - use the Gen 5-specific Glock 26 barrel if you run a later frame. Break-in: Run 50-100 rounds for break-in so the extractor and recoil springs settle on the new barrel. Verify your Glock 26 is Gen 3 or Gen 4 before ordering. 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.
