The Lone Wolf AlphaWolf 9mm barrel is a drop-in replacement for the Glock 19 — Gen 3, Gen 4, and Gen 5 frames. Machined from 416R stainless and salt-bath nitrided for surface hardness, the AlphaWolf line is Lone Wolf's duty-grade option built for round-count shooters.

The matte stainless finish is tougher than standard nitride and holds up to repeated cleanings without wearing through. Factory-spec chamber dimensions handle the full range of 9mm Luger loads — no cast lead restriction.

Specs:

• Caliber: 9mm Luger
• Length: 4.02"
• Fits: Glock 19 Gen 3, Gen 4, Gen 5
• Material: 416R stainless, salt-bath nitrided
• Finish: Matte stainless
• Rifling: Conventional (handles all 9mm bullet types)
• Drop-in install — no fitting required

Confirm your slide is cut to factory Glock 19 spec before install. A 100-round break-in is standard before relying on the barrel for carry. Pairs with any Glock 19-cut slide; not compatible with Gen 5 G19X or G45 length variants.
