Barrels may not be 100% concentric with the bore, these are BLEMS. We have test fired the barrels and have not had any issues but we will not warranty these barrels against baffle strikes or any contact with threaded muzzle accessories. 

Barrels are engraved with 2273 on the hood denoting blemished status.

Upgrade your M&P Shield with our AlphaWolf barrel in .40 S&W. This barrel improves on the accuracy of the factory barrel while maintaining high standards of reliability and function. The AlphaWolf barrel is compatible with both Shield 1.0 and 2.0 models, making it the perfect choice for your gun! Additionally, this barrel is threaded in 9/16x24, so it can mount aftermarket products such as suppressors.

Barrel Features:

  • Fits S&W Shield .40
  • 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)
  • Exacting tolerances allow for drop in installation
  • Fluting creates path for heat and debris to escape
  • Threaded models come with appropriate thread protector installed

*We are unable to custom chamber or port AlphaWolf S&W Shield barrels at this time.

*Non-CA compliant

Do not use +P or +P+ ammunition in any Lone Wolf branded replacement barrel for the Glock 42, Glock 43, S&W Shield or Ruger LC380 series. Between inconsistences with ammunition manufacturers loading practices, which may not conform to SAAMI specifications, unsafe firing conditions may result with these non-standard loads. Accordingly, use of +P or +P+ ammunition in these Lone Wolf barrel models will void the warranty.

    Feeding issue

    Posted by Sean on 6th Aug 2023

    Feeding was no problem with target loads and ammo with smaller diameter hollow points. However my carry ammo has a rather large diameter hollow point for better performance from the lower velocities of a short barrel. I will clean and polish the feed ramp but if this doesn't help I will have to find a replacement ammo.
