I just got a new Benelli M2 semi-auto shotgun. The specs say that the magazine holds 3 shells. I can only get 2 in. The third just doesn't make it in by 1/2 inch. Is there some type of factory plug in the magazine? The manual does not say anything about it.

Dollars to donuts....
Let us know?

The three shells includes the one in the chamber. Waterfowl hunting regs require a plug to keep the total number of shots to three. I believe you can remove the plug if you want. The instructions should be in the owners manual. I have never removed the plug in my M1.

Thanks maineac: There is a factory installed limiter plug in the magazine. The manual was not very clear on that item.
