I am not a shotgun aficionado. I own a Remington 887 Nitro as I got a good deal on it at the time and it seems 'Tacticool' Really I was looking more at capacity as I am not a hunter, just a defender. I believe in using a AR for home defense a lot more than a shotgun, but as a matter of practicality I primarily use hand guns for that role. I carry in the home! That said I am acquiring two more shotguns thru a membership drive at Front Sight. The first is a IAC Hawk 12 Ga Pump, and the second is a Mossberg 930 SPX, a 12 Ga autoloader. Both are Tactical or home defense models. I have used Google, Bing and Yahoo along with You Tube to see a little on these. The Warden and I will eventually attend a shotgun course at Front Sight. I think we need to broaden our horizons and ability and this should be good for both of us. She is going to have to use a 12 Gauge as they are all 12 Gauge.. I don't have enough personal shotgun experience to know which is best for training. I am thinking for that type of a defense course that using the ones with the most capacity (Remington and Mossberg) would be best. Another consideration would be a manual action (pump) would be better. So what are your thoughts for our education? Should we include the Mossberg or not?
