Call me old school since I am circa fn-c2 trained when I was in the forces.
I like this feature about the first shotgun I listed
" Special Purpose Automatic Shotgun, depending on the source). It featured a selective action for greater versatility, and can be used as a gas operated semi-automatic repeater or as a manually operated pump action repeater, depending on the mission and ammunition used"
Nothing like being able to use your gun as a duel purpose by changing it load out by simply carrying 2 types of ammo.
or if you like something more modern go with the spas 15 model
