What does ammo compatibility mean?

Ammo compatibility refers to the ability of a firearm to safely and effectively use specific types or calibers of ammunition. It ensures that the cartridge fits properly in the chamber, aligns with the firearm's design, and functions correctly without causing malfunctions or safety hazards. Using incompatible ammunition can lead to jams, misfires, or even damage to the firearm. Always consult the manufacturer's specifications to ensure proper ammo compatibility.
