Lone Wolf 9mm conversion barrels allow you to shoot 9mm ammunition from your 40 S&W or 357 Sig pistol. These conversion barrels are easy to use and install the same as any other barrel, simply drop it in, no gunsmithing or other modifications are required. We do recommend the use of the correct 9mm magazine with these conversion barrels to guarantee reliable feeding. Use G19 9mm mag for G23 and G32 conversion.

Lone Wolf replacement barrels are manufactured from the highest grade mill select 416 stainless steel.  CNC machined and heat treated, providing a lifetime of service and unparalleled accuracy at an affordable price.  The standard groove and land rifling make this an excellent choice for those who wish to shoot lead, plated or jacketed bullets.  Can be used in factory ported or stock pistol.  Intended for use in the Glock 23 or 32 conversion to 9mm pistol.  Threaded 1/2 x 28 to fit popular suppressor manufacturers.

PLEASE NOTE: Using this barrel in a Generation 4 Glock may cause malfunctions while using the standard Glock recoil spring assembly. For best results, install a 9mm Glock recoil spring found here: Glock OEM Recoil Assembly, or for even more versatility, use our Gen4 guide rod adapter with our Gen3 guide rods found here: Lone Wolf Adaptors and Guide Rods.

    9mm Conversion Barrel

    Posted by Spencer on 16th Jan 2023

    The look is great, the fit into the slide is great, however 9mm will not fit properly into the chamber. I emailed for advice/help and the response was less than helpful and left me wondering if I received the wrong email. I’m not sure if I got scammed or not yet. The other reviews I looked at were all great. Maybe I just got someone on a bad day. As of now I cannot recommend this product but that could change with some good customer service.

Barrel Length:
4.60in (117mm)
