I never said that what's written on the gun made me assume that it takes 2 3/4" shells. I merely posted that info to illustrate the fact that it doesn't specifically say what size shells the gun takes. My assumption was based on info gleaned from a conversation with my CFSC instructor and what I read on this very subject here on CGN by using the (somewhat useless) search function. Erring on the side of caution I thought that it would be a good idea to also post this question, which is what I did. As I mentioned in my original post, assumptions can be dangerous & costly.
