AlphaWolf Barrel Conversion – Glock 22/31 to 9mm, Non-Threaded

The Lone Wolf AlphaWolf conversion barrel (brand part no. AW-229N) lets a Glock 22 or 31 owner run 9mm through the same pistol by simply swapping the factory .40 S&W or .357 SIG barrel, no frame or slide modification required. Machined from stainless steel and finished in black, this non-threaded version measures 4.49 inches and drops into the factory slide just like the barrel it replaces. AlphaWolf barrels are button rifled with a three-stage honed bore, the same process Lone Wolf uses across its full barrel line, and are designed to run lead, plated, or jacketed 9mm ammunition without issue. It’s a fast, affordable way to add a second chambering to a Glock you already own.
