In general, gun magazines are interchangeable. However, there are some notable exceptions.
For example, a 9mm handgun might use a magazine that holds 10 rounds, while a .40 caliber handgun might use a magazine that holds 12 rounds. Some rifle magazines are not interchangeable with pistol magazines because of the different sizes and shapes of the cartridges they hold. Additionally, some manufacturers have unique magazine designs that cannot be used with other manufacturers’ firearms.
If you’re unsure about whether or not a particular magazine will work with your gun, it’s always best to consult with the manufacturer or a qualified gunsmith. They will be able to help you determine if a magazine is compatible with your firearm.
