Upgrade your M&P Shield with our AlphaWolf barrel in .45 ACP. 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 .578x28, 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.
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.
