There is no such thing as a "9mm Beretta" cartridge. Beretta firearms were manufactured in 9x19mm (also known as 9mm Parabellum or 9mm Luger), 9x17 (also known as the .380 ACP), and some models are made in 9x21 IMI for countries which prohibit civilians from owning firearms chambered in military calibres. The cartridge appropriate for your Beretta 9mm should be marked on the frame and slide.
9mm Parabellum
9mm Parabellum- often called 9mm Luger.
380 ACP or 9mm short or 9mm corto
From 1950 onward, Beretta produced several notable models in 9mm, including the Beretta 92, which was introduced in 1975 and became widely recognized. Prior to that, the Beretta Model 951, a single-action semi-automatic pistol, was available since the early 1950s. Additionally, the Beretta Model 1934, while primarily chambered in .380 ACP, was also adapted for 9mm in certain configurations. These models highlight Beretta's commitment to producing reliable sidearms in the 9mm caliber.
Beretta made a LOT of different 9mm pistols. However, if you are asking about the M9 pistol used by the US Army, it is about 8.5 inches long.
First it is Beretta, second, it is a magazine, not a clip. There are several different 9mm models made by Beretta- it will use the magazine made for that model.
