Gen 5 .40 S&W to 9mm Conversion Barrels are HERE!
This video details the installation of 9mm conversion barrels for Glock Gen 5 .40 S&W pistols (Glock 22, 23, 27). The process involves a simple slide disassembly and barrel swap, allowing users to shoot less expensive and lower-recoil 9mm ammunition from their .40 caliber firearms. The presenter, Lenny McIll from Glock Store Performance and Custom Shop, emphasizes the cost savings, reduced recoil, and increased ammo availability as key benefits.
