Lone Wolf Arms AlphaWolf 1/2x28 Threaded 40-9 Conversion Barrel for S&W M&P Shield Pistols

The Lone Wolf Arms AlphaWolf Threaded 1/2x28 Threaded 40-9 Conversion Barrel for Smith & Wesson® M&P Shield Pistols is the ultimate aftermarket caliber conversion barrel for the competitive target shooter or tactical operator. Manufactured to extreme tolerances for a tight lockup and better fit than factory Glock barrels, this drop-in upgrade features stress-relieved and heat-treated 416 stainless steel construction with a corrosion-resistant SBN (Salt Bath Nitride) finish for maximum strength and natural wear resistance. 1/2x28 threads allow users to quickly attach direct-thread suppressors, pistons, and other muzzle devices while strict machining specifications and manufacturing tolerances safely convert your .40 S&W-chambered pistol to fire most 9mm Luger loads without any permanent modifications or expensive gunsmithing. The 3-stage honed bore is polished for smooth and reliable performance, while precision-machined button rifling delivers match-grade accuracy. Plus, a proprietary fluting pattern creates a path for heat and debris to escape, resulting in a longer-lasting service life with minimal wear. No gunsmithing or custom fitting is required for installation. Includes thread protector. Made in USA.
