Description
Product Overview
Convert your .40 S&W or .357 SIG handgun to shoot affordable 9mm Luger ammunition with the Lone Wolf Distributors AlphaWolf 9mm Conversion Barrel for Glock 22 & 31. Precision-engineered in the USA from certified 416R stainless steel, AlphaWolf barrels set the standard for match-grade accuracy, combat reliability, and long-term durability.
Featuring a button-rifled, three-stage honed bore, this stock-length conversion barrel is safe for lead, plated, or jacketed factory ammunition. The strategic exterior fluting aids in weight reduction and rapid heat dissipation, while the deep Salt Bath Nitride (QPQ) finish provides exceptional resistance to corrosion, friction, and surface wear across all Glock generations.

Neither Lone Wolf Distributors nor Terran Gear USA are affiliated with or endorsed by GLOCK, Inc. or GLOCK Ges.m.b.H. Note: Converting a G22 or G31 to 9mm requires 9mm Glock magazines (e.g., G17 magazines).
Key Features
- Simple Drop-In Conversion: Effortlessly converts .40 S&W (G22) or .357 SIG (G31) handguns to shoot 9mm Luger ammunition without slide modifications.
- 416R Stainless Steel: Forged and stress-relieved 416R stainless steel construction ensures target-grade precision and long barrel life.
- Salt Bath Nitride Finish: High-hardness SBN/QPQ treatment penetrates the metal surface for superior corrosion, wear, and chemical resistance.
- Button Rifled & Honed Bore: Three-stage honed bore allows safe shooting of lead, cast, plated, or jacketed bullets.
- Exterior Fluting: Custom wave-fluting removes non-essential outer mass to enhance heat dissipation and aesthetic appeal.
- Multi-Gen Compatibility: Engineered for a precise drop-in fit across all Glock Generations (Gen 1–5).
- 100% Made in the USA: Proudly manufactured, machined, and finished in the United States.

Frequently Asked Questions
Do I need to change any other parts to convert my Glock 22 or 31 to 9mm?
You will only need to swap to 9mm magazines (such as standard Glock 17 magazines). The conversion barrel is specifically profiled to fit the wider slide bore opening of a .40 S&W or .357 SIG slide without needing to change the slide or recoil spring assembly.
Can I shoot unjacketed cast lead reloads through an AlphaWolf barrel?
Yes. Unlike factory Glock polygonal rifled barrels, AlphaWolf barrels feature traditional button rifling with a 3-stage honed bore, making them safe for raw lead, hard-cast, plated, or copper-jacketed ammunition.
Will a standard 9mm barrel (like a G17 barrel) fit in my Glock 22?
No, a standard Glock 17 barrel has a smaller outer diameter and different locking lug dimensions than a G22/G31 barrel cut. You must use a dedicated conversion barrel like the AlphaWolf, which is thick-walled to fit the G22 slide correctly.
Is this barrel compatible with Gen 5 Glock 22 pistols?
Yes, Lone Wolf AlphaWolf barrels are machined to fit across all generation models, from Gen 1 through Gen 5.
