My first (all mine) real gun was a 12 ga. I think shotguns still get a lot of well deserved respect, but they aren't the "cool" gun of the moment like the AR 15 platform. I think the accessory availability after the assault weapons ban was lifted and the mass purchasing of them out of fear of a new one has helped to make them the current "it" gun.
If I could only have one gun, I would pick a mid-barrel length 12ga pump. With the proper ammo choice, it is capable of taking everything from small game/birds to large animals at respectable distances. For home defense, I would argue that a shotgun is hard to beat. I have the aforementioned 12 ga loaded with 8 shot as my goto home defense gun.
When funds allow and I knock off a few of the other guns on my list, I plan to get a short barreled shotgun for dedicated home defense. My current one has to pull multiple duty as a hunter too, and I don't want to take away it's hunting abilities at the moment.
I love my BCM Middy, and my M1A, and I am currently jones'n to build a 18" bolt action .308 wood stock "do it all" rifle, but I am starting to think a 20 ga auto loader with a cut down barrel may be the more pragmatic choice.
What do you think?
If you don't have a good shotgun, I say go for it. My questions to you are: Why 20 over 12? Is an autoloader a must? and What are you thinking for stock options?
I think a 12 ga pump offers more versatility. I also think shotguns need a shoulderable stock. All just my opinion.
Clyde Barrow (sp?) (Bonnie and Clyde) had an affinity for the shotgun. Look up one of his "whipit" guns.
