I am in the process of helping my parents train with a handgun for some home protection. After much talk about shotguns falling on deaf ears I finally convinced them to get a Shotgun as well. My original plan was to get a Remmington 870 in 20 gauge BUT then I read the below article. I don't understand why the 870 would be so loved in 12gauge and not in 20gauge (my plan for my parents). Any incite would be appreciated. I guess the Mossberg 500 Special Purpose would not be a horrible choice either. http://www.chuckhawks.com/ammo_by_anonymous.htm Wanna kill these ads? We can help!
