Why buy a 9mm Conversion barrel for the Glock 40 Caliber?
Installing a 9mm conversion barrel on a .40 S&W Glock (like the G23) offers significant advantages, including lower ammunition costs and reduced recoil for faster follow-up shots. Conversion barrels are specifically engineered with thicker walls to match .40 slides, unlike standard 9mm barrels. Wheaton Arms barrels feature standard rifling and a target crown for improved accuracy and versatility with various ammunition types.
