Frequently Asked Questions
Will this magazine work with any other Mossberg shotgun models?
No — this magazine is designed exclusively for the Mossberg 590M mag-fed shotgun. It will not fit standard tube-fed Mossberg models such as the 500 or 590. Always verify your specific firearm is the 590M variant before purchasing.
Can I use 3-inch or 3-1/2-inch shells with this magazine?
This magazine is rated for 2-3/4" 12-gauge shells only. Using longer shells such as 3" or 3-1/2" magnum loads is not supported and may cause feeding failures or damage to the magazine. Stick to standard 2-3/4" shells for reliable, safe operation.
Is this magazine legal in California, and are there capacity restrictions I should know about?
Yes — this magazine is blocked to a 10-round capacity, making it compliant with California's magazine capacity laws as currently enforced.
