A shotgun is harder to navigate hallways with. However, unless you have been trained to breach doors and clear buildings, your best course of action in the event of a break-in is to lock yourself in your room and phone the law.
You're making major unfounded assumptions here, John.
Who said anything about breaching doors and clearing buildings?!
I'm talking about something along the lines of her sitting in her living room with the shotgun in the corner. Multiple armed assailants bust down her front door and are virtually on top of her almost immediately. There's no time to run to a "safe room". Home invasions go down surprisingly fast, so "grab and shoot" is often your only option.
Being that she's inexperienced with firearms of any type, and a small-framed woman with small hands, a 7.5 pound shotgun that's forty inches long doesn't move as quickly in her hands, as it would in the hands of a grown man who's physically larger, stronger and more experienced with shotguns.
For this purpose, a shotgun is almost impossible to beat. It's plenty maneuverable enough to cover the doorway from across the room and affords you the power to shoot through the door, if necessary.
That's assuming she's lucky enough to make it to her room. Since the thugs aren't going to call ahead and advise her when they intend to forcibly invade the house, she's going to need close-by protection no matter where she's at in the house.
Handguns are much more maneuverable and portable. They can be easily carried on your person around the house, and easily placed on the dinner table, coffee table, bathroom counter and virtually anyplace else.
What if she has small bathrooms in her house, and the perps invade while she's in one of them? I've got small bathrooms in my house, and I wouldn't want to get "caught on the pot", trying to handle a 40" shotgun in a tight space.
Recoil is quite managable with a semi-auto 20 gauge S/A such as the SAIGA. I would feel confident with a .410. If you are concerned about over-penetration, #4 (turkey) loads should work quite well.
Quite manageable for YOU. That doesn't mean it is for a small woman with no experience. She might be scared to death of shotguns to begin with. I've seen women on Youtube who've never fired a shotgun, and I've seen the "deer in the headlights" gripping fear in their eyes when their husbands/boyfriends attempt to goad them into shooting it.
With proper instruction/practice, a woman can become quite skillful at firing a shotgun. But a shotgun is NOT a good beginner's weapon for people who have no experience with firearms of any kind, whether male or female.
Also, many prominent self-defense experts advise that the .410 shotgun and birdshot are poor choices for self-defense. They've both been proven inadequate in many instances, some of which cost the people using them their lives.
A high capacity 9mm semi-auto pistol is her best bet right now. Hopefully she'll get professional instruction and practice regularly for a year. After that, she can start thinking about a shotgun or larger caliber handgun, if she wishes.
