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.

*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.
