Lantac USA 9INE Threaded Barrel for Gen 3 / 4 Glock 19 Pistols

A drop-in pistol barrel upgrade, the LantacA(R) USA 9INE Barrel for GlockA(R) Gen3/Gen4 19 Pistols is designed to deliver superior accuracy, improved handling, and consistent stopping power with any standard or +P 9mm load. Manufactured through a proprietary machining and cut rifled process, the 9INE G19 threaded barrel features certified, DFARS-compliant 416R stainless steel construction with a 1:10 twist for superior strength and accuracy. LANTAC's proprietary and patent-pending fluting pattern reduces weight for smooth handling without sacrificing consistency or durability. The 6-groove and 1:10 twist, coupled with the fully inspected and double-honed design, ensures maximum accuracy with a bore maximum Roughness Average (RA) of 12. The chamber is machined to Match-Grade SAAMI specifications and polished to a maximum Roughness Average (RA) of 16. This barrel is stress-relieved after rifling for additional strength capable of handling super-hot +P ammunition. Final dimensions are held to a +/- 0.0002" deviation for maximum consistency, accuracy, and quality. All 9INE-series Barrels are designed to deliver a drop-in fit and do not require gunsmithing or permanent modification for installation. Includes a removable thread protector.
