The Glock 19 Gen 4 is discontinued for the U.S. commercial market, but not for the law enforcement or international markets. Glock has stopped producing 9mm and .40 caliber Gen 4 models for the U.S. civilians, focusing on the Gen 5 models instead. However, Glock still supports fielded Gen 4 pistols and agencies with Gen 4 models, and continues to manufacture Gen 4 pistols in other calibers and for other regions.
