Well, just a word about that: in a home-invasion scenario, a handgun may be just as detrimental to your protection as a Byna would be. The reason is:
1. In a home invasion situation, it is more likely to take place at night; the thug does not want to be seen in broad daylight, so he makes his entrance under cover of darkness. The problem is, even if you know somebody's in the house, they're hard to see, because it's dark. Turning on lights is detrimental, for two reasons: A, if you can see him, he can see you. Light makes it easier for him to target you when he has clear vision. B, lights flashing on might startle the intruder, causing him to start busting caps out of panic. So keeping it dark actually works to your advantage; an extra word of caution on that below.
2. Because the intrusion is taking place at night, it's not only hard to see, but you have the added aspect that you may be fuzzy from sleep, not at the top of your game. And there are a lot of nooks and crannies inside a home for a thug to hide, so you might fire a few rounds from a handgun and completely miss your target. Which brings us to:
3. The best weapon for interior home defense is a shotgun, not a handgun. For all of the reasons I just outlined above, a shotgun is much better choice, because it does not fire a small chunk of lead that makes a pencil-sized hole in whatever it hits---it literally
sprays an area with lead or steel pellets in a wide pattern. Ergo, if you know where the thug is, even if he's hiding behind a cabinet or something, when you fire a shotgun in his direction, even if you miss, you're likely to get some of him; when he reacts to getting hit, it gives you the chance to administer the
coup de gras.
4. The extra caution I mentioned: since you never fire a weapon at anything that you do not intend to harm or kill, when you hear an intruder inside your house, the first thing you do after retrieving your weapon is to
check the location of everyone who's supposed to be in the house. When you have determined that your kids are in their rooms and your spouse is in bed, then you know that whoever is down there in the living room is an intruder. This means that you have fewer qualms about shooting in the dark. As I said, a shotgun sprays pellets over a wide area, so it's reasonable that you can simply aim in the general direction of the noise or the shadow and discharge the gun. I would recommend a
pump shotgun, so after you discharge one shell, you can quickly rack another one into the chamber if you have to. Something like a single-shot squirrel gun is not what you want; if you have to break open the breech and fumble for another shell, load it, snap the breech closed, and re-aim to fire, you're wasting precious seconds which might allow the thug or his accomplice to overpower you. With a pump, it's "bang!---
pump---bang!---
pump---bang!" as many times as you need until your target is neutralized.
The shotgun I would recommend is a 20-gauge, loaded with .00 (double-aught) buckshot. Anything smaller, like a .410, won't have enough stopping power, and anything bigger, like a 12-gauge, is usually too much gun for the average-sized woman to handle easily. And buckshot ensures you have enough power in the shot to take the attacker down; something like birdshot or a skeet load does not have the power you need. A shorter barrel is better, since it means your spread will be wider; but check your local laws, because a shotgun barrel that's
too short will probably be illegal.
And finally, bear in mind that when you do take the intruder out, you're going to have one really nasty mess to clean up afterwards. Buckshot pellets shred whatever they hit: furniture, drywall, wooden floors, it will all be splintered and pulverized once your shot hits. And, sad but true, that also includes the thug. He will be shredded as well, and you're going to have a bone-blood-gristle-eviscera spray that will go all over the place in a big splash, and once he goes down, he will bleed out all over your floor. A human male usually contains about 4.5 to 6 pints of blood, so you're talking about anywhere from half to three-quarters of a gallon of blood that you'll have to have cleaned up afterwards. This is a nasty, unpleasant aspect of the whole business, but on the plus side, you and your family will be alive and safe. You can replace furniture, flooring, and drywall; you can't replace a murdered child, and you can't un-rape yourself if the thug gets the chance to commit either atrocity.
So: for street use, probably a 9mm automatic pistol with at least a 12-round magazine (preferably loaded with law enforcement-grade hollow points), and for home protection, a 20-gauge pump shotgun loaded with buckshot.
