I guess a case is good for transporting to/from the range or hunting camp. I prefer to keep mine more ready-to-use than having to open a case to get to it. But, on the other hand I guess it doesn't matter how many firearms you have in your arsenal, you will only use one in a surprise self-defense situation. Just have to decide ahead of time which one it will be.
I have a case for my sks which does not fit now that I have a scope on it. The 995 or 4095 would fit easily in it, but I have not decided to close either of them up yet.
