Frequently Asked Questions

Will this magazine fit all MKA 1919 shotgun variants?

This ProMag magazine is specifically designed for the MKA 1919 semi-automatic 12-gauge shotgun platform. It is recommended to verify your exact model variant before purchasing, as minor generational differences in the MKA 1919 lineup can affect fitment. When in doubt, consult your firearm's manual or contact ProMag customer support.

Why does a 10-round magazine come in a 15-round body?

This magazine uses a 15-round physical body that has been blocked and pinned internally to limit its actual feeding capacity to 10 rounds, making it compliant with California's magazine capacity restrictions. The larger body size is a result of the original magazine design — the internal block ensures it meets state law while maintaining the same exterior form factor.

Is this magazine legal to purchase and use in California?

Yes — this magazine is specifically configured for California compliance, with its capacity permanently limited to 10 rounds. California law restricts the sale and possession of magazines capable of accepting more than 10 rounds, and this ProMag product is designed to meet that requirement. Always verify current state and local regulations, as laws can change.
