Lone Wolf Distributors is not a newcomer to the world of Glock aftermarket parts. This Idaho company has been around since 1998 and is well-known for manufacturing nearly all of its items in-house, from raw materials to finished products.

The AlphaWolf Threaded Barrel series is one of the highest-quality, fully-featured lines of aftermarket Glock barrels you can find today. These 416 stainless steel barrels are coated in a standard black nitride finish and fluted for better dissipation of heat during sustained firing.

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.

The Radical Firearms Glock 34 Threaded Barrel is a 5.3”, no-frills threaded barrel, suitable for target or competition shooting use at a budget-friendly price.

The standard black finish and stock-like appearance do not significantly alter your firearm’s looks. This is ideal if you prefer a stock Glock style but would like to benefit from the advantages of aftermarket parts.

With the standard 1/2-28 threading, this barrel is ready for any muzzle device, such as a suppressor or a muzzle brake. Although this item is intended for use in the Glock 34, you can drop it in a Glock 17 as well. Roughly 0.8” of the barrel sticks out past the slide.
