Cartridge information is primarily identified by the data stamp on a firearm. The data stamp is typically located on the barrel or receiver and provides critical information about the firearm, including the manufacturer, model, caliber, and sometimes the country of origin. This information is essential for ensuring that the appropriate ammunition is used in the firearm, as using the wrong caliber can lead to malfunctions or dangerous situations.

Chamber design does play a role in determining what cartridges can be used, but it does not provide a specific identification like the data stamp does. The design of the chamber helps define compatibility with certain cartridges but does not serve as a labeling mechanism.

Barrel length refers to the measurement from the breech to the muzzle and can influence a firearm's performance but does not convey information about the specific cartridge it uses. Similarly, trigger pull weight is related to the firearm's mechanism and how it operates, but it too does not identify cartridge information.

Understanding the significance of the data stamp can enhance safety and specific knowledge about a firearm, making it a crucial element for firearm users.
