A lot of people get Galand and Perrin cartridges confused, so we will take a look at these French thick rim cartridges over a few upcoming articles. The 9mm French thick rim cartridges are the most straight forward so we will start with them. Above all, the important take-away from this article is that, even though it is repeated in various articles and references, there is no such thing as a “Galand-Perrin” revolver. And these cartridges were never meant to be interchangeable nor were they ever designed to be used in the same guns.
What is a Perrin Cartridge?
A Perrin cartridge is an early centerfire cartridge invented by Louis Perrin in 1859. It was designed as an internally-primed cartridge which had a percussion cap resting in a metal anvil or frame inside the cartridge.
