Alpha Wolf barrels establish the benchmark for absolute accuracy and combat reliability. It is the pinnacle of what every other barrel manufacturer strives to be.

Barrel Features:

  • PROUDLY MADE IN THE USA!!
  • Fits all Glock generations, except Gen5
  • Designed for lead, plated, or jacketed ammunition
  • Certified, stress relieved 416 stainless steel
  • Button rifled, three stage honed bore
  • Industry recognized SBN premium coating (SBN is Salt Bath Nitride, similar to Tennifer)
  • Heat treated to RC 40-42, then SBN coating increases surface hardness to RC 60
  • Exacting tolerances allow for drop in installation
  • Fluting creates path for heat and debris to escape
  • Threaded models come with appropriate thread protector installed

Due to SBN coating we are unable to custom chamber or custom crown Alpha Wolf barrels.

    G40 Alpha Wolf Threaded Barrel

    Posted by Mark Keiser on 26th Nov 2025

    This is my second Lone Wolf barrel purchase, the other is my G21. Both barrels are noticeably more accurate than the factory barrels at distances greater than 10 yards.

    Not feeding next round

    Posted by derrick/ Customer Service on 2nd Nov 2023

    see other review, I am having the same feeding issue in my g40 Customer has been contacted and will receive a full refund once the barrel is returned. FTF is usually caused by the maximum supported chambers of our barrels.

    Wont feed Sig target ammo

    Posted by edward leonard on 4th Nov 2022

    So far this barrel works ok. It is a tight fit but it fits. I have tried 2 target types of target ammunition in it so far. Federal red box (1030 fps advertised) and Sig Sauer Elite Performance (1250 fps). Both 180grn. Without the surpressor the barrel won't feed the Sig at all but feeds the Federal fine. With the supressor it feeds both. The failure is in chambering the next round in the magazine. The round gets hung on the upper part of the chamber.
