I am applying for a shotgun certificate and have a query i hope you may be able to help me with.

I've previously shot pigeons on land accompanied by other shooters and the gun i used (Beretta) held three cartridges - can't recall the model unfortunately.

This is the type of shotgun i hope to acquire. Can i own this type of shotgun with a basic shotgun certificate. Is this is what is meant by a "semi-auto"? And do i need a FAC for this?

I'm sorry if this question sounds very basic, but I'd really appreciate your help.
