Agree with both the 410 and the 380.; and would not change!
The Colt 1911 is still basically the same gun today and many more were designed around it. Same goes for a DA revolver so modern isn't necessarily better.
I've been reading many discussions between the 9mm and the 380 and have even been watching ballistic videos so the question to me is between stopping power and deterrence. At 20' a 22 cal. rim fire can kill a person. A 9mm will still pass thru 6 sheets of drywall with ease.
Way back then we used to load 357 with 158gr. lead hollow base wadcutters and load them upside down with light charges. What a load! We also used to take plastic bags like from the grocery store and pack them full of newspaper and then soak them in water until they'd swell and the plastic bag would stretch tight. That's what we used for ballistic testing as we didn't have gel. That wadcutter was easy to shoot and had a horrific impact. As I recall it was only traveling at about 650fps. Granted at 50' it had zero energy left, but at 20' or less, WOW. Same could be done with the 44 mag.
I think more important than ballistics is the ability to get the weapon quickly on target and accurately control multiple shoots.
People are surprisingly inaccurate with a handgun under stress. My vote would be a shotgun of the largest gauge she can handle, loaded with something like #6 shot or smaller to prevent hitting someone in the next room/house.
just a wild guess, but you do have a flair gun in your boat? Bring it in the house, better than nada. And it is a 12ga slug of sorts, with what recoil? ha Light, legal without a permit, and will leave a nasty wound if nothing else. PLUS, you can see if you hit 'em!!!! ound:
.22 can kill someone, yeah, so can a rock, or a screwdriver.
Completely agree. A lot of people will be shaking like a leaf knowing they have to pull the trigger. A shot gun lets you just get close to your target and will do a lot of damage. A pistol, you will have to be much more accurate. Shot gun hands down. And as mentioned, there's something to be said about chambering a shell that may put the shiver in the perps timbers..... A 12 gauge with #6 shot should do the trick. Yeah, it will kick, but in the heat of the moment she won't care nor will she feel it....20 gauge will work too and is much lighter and will still pack a good enough punch to mess the perp up....
