    Instead of using polygonal rifling like on stock Glock barrels, AlphaWolf barrels employ traditional button rifling, allowing you to use unjacketed lead ammunition. If you reload and make your own bullets, it’s the ideal platform to shoot them with.

    Available in a wide range of calibers and barrel lengths to fit most Glock models, the .40 S&W and 10mm versions use 9/16×24 threading, while all other models use standard 1/2-28 threading. All are suitable for suppressors and other muzzle devices.
