Also, as a side note, fighting with a shotgun is easy but also very hard to master. Pump shotguns are exceptionally reliable, powerful, versatile tools, but, you must know how to run then. In truth, an AR15 is really the simplest, best tool for most jobs of self defense, but, it's much more expensive than a used Mossberg (I only recommend Mossberg 590s or 590A1s drive Remington has gone to complete crap after the mess that recently happened. A used 870 that was made before everything went to pop is a fine option, but, I prefer the ergos of the 590 UNLESS you want a pistol grip, but I don't recommend that in most cases)
