History
Adopted by the Italian Army in 1874 for the Chamelot-Delvigne revolver, later transitioning to the Bodeo M1889. The Bodeo M1889 served Italian officers and NCOs through WWI and WWII — an extraordinarily long service life for a 19th-century design. The cartridge's moderate performance was supplemented in WWII by widespread use of captured 9mm Glisenti and 9mm Luger pistols. Original Italian military ammunition is an antique collectible.
