The Pistola Automatica Modello 1910, often referred to as Glisenti Model 1910, was a 9 mm calibre semi-automatic service pistol developed by Bethel Abiel Revelli for Società Siderurgica Glisenti and produced by the company Metallurgica Bresciana già Tempini. It was put in production in 1909-1910 to replace the aging Bodeo Model 1889 still used by army officers. It saw extensive service in World War I and World War II with the Royal Italian Army. The Model 1910 has a complex and weak firing system which mandates that the pistol ought to use a weaker version of the widespread 9x19 Parabellum.
