Glock gave us the model 23 in 1990—an incredibly significant year in the firearms industry. First, was the introduction of the .40 S&W caliber. Collaboration between Smith & Wesson and Winchester, gave the world a 185-grain bullet that flies over 1,000 feet per second—a cartridge with nearly perfect balance of weight, mass, firepower, and consistent energy transfer. The FBI needed a gun to fit the new round and Glock answered the call with the models 22 and 23. The Glock 22 is full-sized, while the 23 is the compact model. Inspired by the Glock 19, the Glock 23 shares the same specifications as the iconic 19, except for the difference in caliber.
