050806113176 The Brownells Match-Grade Conversion Barrel enables you to switch your .40 S&W chambered Glock® 23 to shoot 9mm Luger (9x19mm) ammo AND also improve its accuracy potential at the same time. It fits Gen1 through Gen4 variants of the Glock® 23, and will be a drop-in install on most guns. Each conversion barrel is machined from 416R stainless steel alloy to precise dimensions to ensure a tight lockup and long service life. Button-rifled with 1-10" right-hand, 6-groove rifling that is compatible with inexpensive "practice" ammo that has non-jacketed bullets. The hard Black Nitride finish resists surface wear and stops in its tracks whatever corrosion might try to challenge the stainless steel. 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. Fits Glock® 23 Gen1 thru Gen4 G19-compatible 9mm magazine required to complete the conversion (not included) Extra-strong 416R stainless steel alloy Matte black Nitride anti-corrosion finish Button-rifled 1-10" twist Threaded model has 1/2"-28 tpi threads If you have an old Glock® 23 with a shot-out factory barrel, give it a new lease on life. 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 will need to add a Glock 19 compatible 9mm magazine.
