The name 'combat shotgun' should be a substantial hint.
Unless the deer you're after is breaking in to your home or hiding in a crack house, this is not the weapon that you want. Think along the lines of specific tools for specific needs. The weapon you illustrate is for up close, closed quarters 'social work'; for 'hunting' two legged critters.
If you want a shotgun that can fill both the 'home defense' and hunting roles, get a Remington 870 with two barrels; an 18 or 20 inch for home and a 26 inch or longer for field work. The 870 can be bought used and in good shape for around $200.00 and a second barrel will cost about half that. Avoid pistol grips, tactical add ons and all of the other combat bling. It only adds more weight and as no place in the hunting field.
Whatever you buy, get lots of ammo and practice often.
