Give your old-gen Glock® pistol the performance upgrade it deserves with the Lone Wolf Arms AlphaWolf Barrel for Gen 1-4 Glock® 20L/40 .40 S&W Pistols. Manufactured to ultra-tight tolerances for drop-in installation and a precise fit and finish, this 6.02" barrel features stress-relieved 416 stainless steel construction, heat-treated to RC 40-42 hardness and finished with a corrosion-resistant SBN (Salt Bath Nitride) coating for extreme strength and durability. The bore is polished and honed, while precision-machined button rifling delivers match-grade accuracy with most factory .40 S&W loads, including lead, plated, and jacketed offerings. Plus, the proprietary fluting pattern reduces weight and facilitates faster cooling. Made in USA.
