I knew where you are coming from. Now for all you Nay sayers here is some personal experience. Not hear say or media spun Bull.
My wife is not one of those 100 lbs. soaking wet women but by no means big (look at my previous posts for pictures if you don't believe me). She and I have hunted together for the past 8 years. 6 of which she has used a shotgun.
Now her and I went to the range the other day and shot our shotguns, and some "assault" style rifles (not mine). She shot the shotgun with her sabot slugs took care of business shooting a great group out to 100 yards. She then shot the "Assault" style rifle a little reluctant at first because they can look intimadating. And here is what she said I quote "This would make a great hunting and self/home defense gun." I asked her why and i quote again "It is light, easy to maneuver, simple to use, and DOESN'T kick!"
Now I would feel 100x more comfortable with my wife using an "assault" style weapon to defend herself compared to the shotgun for the simple reason that she can handle it much easier than the shotgun meaning she will more likely hit what she is aiming at.
Now call BS if you like but my buddy and I both heard right from her mouth.
EDIT: Her shotgun is a 20ga 1187 synthetic stock and the Assault style rifle was .223 and the other was .308
