Distinguishing Between 9 mm and 7.65 mm Parabellum on the Fly

Kyrie · 03-19-2018, 05:35 AM

Gentlemen,

IMO the simplest method is to try an insert a round of .32 ACP ammunition into the muzzle of the Luger.

If the Luger has a 9x19 mm barrel the .32 ACP cartridge will slip into the barrel right up to the semi-rim on the cartridge casing.

If the Luger has a 7.65 mm barrel the .32 ACP cartridge will stop before the case mouth enters the bore.

Best,

Kyrie
