The Lone Wolf AlphaWolf conversion barrel transforms your full-size Glock 22 or 31 into a cost-effective 9mm shooter without changing frames. Built from stress-relieved 416 stainless steel and heat-treated to RC 40-42 hardness, this barrel offers the durability you expect from Lone Wolf's lineup of American-made components. The proprietary salt bath nitride coating increases surface hardness to RC 60, providing excellent corrosion resistance for years of shooting.
This barrel features button rifling with a three-stage honed bore that delivers consistent accuracy from round to round. The proprietary fluting pattern reduces weight and helps with faster cooling during extended shooting sessions. The chamber is designed with factory-level tolerances, allowing for straightforward drop-in installation without gunsmithing. Threads are 1/2×28, compatible with most popular suppressors and muzzle devices, and a thread protector is included.
Works with all Glock 22 and Glock 31 generations (Gen 1-4). The barrel accepts lead, plated, and jacketed ammunition, giving you flexibility with ammo selection. For optimal performance with Gen 4 pistols, Lone Wolf recommends using a 9mm recoil spring instead of the standard .40 S&W spring. Pair it with magazines designed for Glock 17s for reliable feeding and ejection. At 5.03 inches, this barrel maintains stock length proportions, so it won't extend awkwardly from your slide.
Every component is proudly manufactured in the United States. The exacting tolerances and meticulous quality control make this conversion barrel a practical upgrade for those wanting to run cheaper 9mm ammo through an existing .40 frame without sacrificing reliability or accuracy.
Yes, this barrel is designed for Glock 22 and Glock 31 pistols from all generations (Gen 1-4). It's a true drop-in design, so you won't need gunsmithing to install it. Gen 4 owners should consider using a 9mm recoil spring for best results.
Absolutely. The barrel features 1/2×28 threads, which is the most common thread pattern for 9mm suppressors. A thread protector is included to keep the threads clean when you're not running a suppressor.
The button rifled design with standard rifling allows you to safely fire lead, plated, and jacketed ammunition. This is a major advantage over factory Glock barrels that use polygonal rifling, which can be problematic with lead rounds.
For Gen 3 pistols, the barrel often works fine with the factory spring. For Gen 4 pistols, Lone Wolf recommends using a 9mm Glock recoil spring instead of the standard .40 S&W spring for optimal feeding and reliability. Use magazines designed for Glock 17s for best results.
