I just received my Camo 26 inch LH SBEII. In reading the manual - loading. The manual indicates that the magazine can hold 3 - 3-inch or 3- 2 3/4 inch rounds. With one in the chamber that is 4 rounds. For duck hunting, I normally use 3 inch rounds and we are limited to 3 rounds. ------ Is there a plug that can be installed to limit the number of rounds to 3? I know that I will be checked sometime this upcoming season.
