I modified my five and one Mosberg 500 to shoot the little Aguila minishells. It will now hold ten rounds. The next project will be to modify the seven and one to hold about fourteen rounds. It’s pretty simple to do. Just lengthen the tang on the elevator. You might have to put a slight downward angle on the end.
Thanks for the advice! A lighter load (easier on the wrist) and more shots/magazine to boot!
I had a look at the minishell pages on the Aguila website. The potential for jamming even the modified Mossberg is a concern to me; it might be better for me to go with the Winchester Defender 1300 (18"), since Aguila's testing indicates it works well out of the box with the 1 3/4 shells... you think?
