Hi yall I've recently moved to SC, living by myself, this is my first post. I have been trying to buy a shotgun for home self defense I've done my homework on google, Sportsmens warehouse, etc, but couldn't find the perfect one for you. and.. there's this part of me some of the members here is far better knowledgable than gun shop employees so,,, here they are. 1. semi auto (i do not want to pump between shots) 2. powerful penetration i.e. say, a bugglar runs away with something that belongs to me, I wanna shoot through my steel door and drywall, and still get him good also, if the bad guy is trying to get away in a vehicle, I'm looking for something to punch a hole in the car from the trunk lid all the way up to the front seat, to the bad guy. 3. easy maintenance I don't have time to clean and oil my gun every day, but I DO UNDERSTAND the importance of maintenance. just sayin, the less, the better. 4. multi-purpose i won't go clay shooting with semi-auto LOL but,, hunting, etc. you get my point. 5. easily maneuverable I'm not quite sure on this one,,, I like heavy guns kicking nice and deep. but also has to be light enough so i can sprint 1/4mile carrying it but too light will end up being snappy so any input is greatly appreciated thanks everyone in advance!
