It's a nice idea to have a one-does-it-all shotgun but in the long run it never works out that way. Practically, you could get a Mossberg 500 with maybe an extra 18.5" bbl and have everything covered BUT....
if you're like most on this board--with time and as you accummulate more $$$
you will want this different shotgun or rifle or handgun. You won't necessarily NEED it but it serves a purpose better than what is in your present inventory. I do understand the idea behind a starter gun that can work for every application. Welcome to the journey, it's expensive but oh so fun---see you when you are 65.
