I'm looking into a home defense shotgun for my house. Nothing crazy but it needs to be 20" or under. I've been looking at the remington 870 tacticals or a winchester 1300 but I'm not too certain on either. I can get the remington in OD green with a 20" barrel and pistol grip stock for $380. I'll be adding a surefire light, heatshield, and some form of shell holder. Anyone have some suggestions?
