Brownells 75th Anniversary - A Shooting Heritage

Convert a .40 Caliber Glock? to 9mm AND Also Improve its Performance!

This drop-in Match-Grade Conversion Barrel enables you to change your .40 S&W chambered Glock® 22 to shoot 9mm Luger (9x19mm) ammo. It's machined from high-grade 416R stainless steel alloy to precise dimensions to ensure a tight lockup for improved accuracy potential. The hard Black Nitride finish resists surface wear and stops in its tracks whatever corrosion might try to challenge the stainless steel.

Our match conversion barrel fits Gen2 through Gen4 variants of the Glock 22, and will be a drop-in install on most guns. Button-rifled with standard, 1-10" right-hand, 6-groove rifling that is compatible with the non-jacketed bullets found on some inexpensive "practice" ammo.

Available with either a Plain muzzle or Threaded (1/2"-28 tpi) to enable installation of a compensator or sound suppressor. Both have an 11-degree target crown, and each is laser engraved with the chambering and the Glock model it fits.

  • Glock® 22 Gen2 thru Gen4
  • G17-compatible 9mm magazine required to complete the conversion (not included)
  • Extra-strong 416R stainless steel alloy
  • Black Nitride anti-corrosion finish
  • Button-rifled 1-10" twist
  • Threaded model has 1/2"-28 tpi threads

Got a Glock® 22 with a shot-out factory barrel? Swap in a Brownells match-grade conversion barrel and enjoy the gentler recoil and lower cost of 9mm ammo. Remember: to complete the conversion, you'll also need to swap in a Glock 17 compatible 9mm magazine.
