So, I'm new and already own several firearms, including handguns, one shotgun and some rifles. In the short time i have been doing every thing that i can to learn, i have noticed that there is consensus that the shotgun is generally accepted as the best weapon for HOME deffense, right.... So when i go to sleep, my mossberg 500 is the one that i keep closest to me. Rescently aquired 2 new rifles (at least new to me), one a .308 cal, the other chambered for .223 and found myself falling in love with shooting my rifles! And start thinking that i use my shotgun as my primary home deffense weapon, not because i "know" that it is actually my "best" option but because most people who are into firearms think so! I'm aware that there must be a reason for that but when i ask myself why is a shotgun by my side, better than an AR or better than an AK by my side, i (and please remember that I'm a rookie) cannot come up with an answer. So let's hear it from the experts out there, why is the shotgun the best weapon for HOME defense? (compared to a rifle) Oh, one last thing, I live in Puerto Rico, where most homes are built in concrete so wall penetration and killing your neighbor is almost not an issue. So please enlighten me and others that may have asked themselves the same thing!
