What shotgun works best for home defense?

[Alan]

I've been eyeing shotguns for home defense and could use some input from those who've been there. I'm stuck between a 12-gauge and a 20-gauge. I get that the 12-gauge packs a punch, but I've heard the 20-gauge is easier to manage, especially in tight spaces. What's your take?

What should I focus on when it comes to barrel length and stock setup for a home defense shotgun? I'm looking for something straightforward and reliable — any specific models or brands you trust?

And what about training? I've shot a shotgun before, but it was just casual. How should I be prepping if I want to feel confident when it counts?

Hard to beat an 870 12 gauge with 18" barrel.
If price is a concern, look for a Mossberg Maverick 88, can be found around $200 and up.

I have 2 in my bedroom at all times. A Mossberg 500 12gauge and a Tokarev TAR12 12 gauge. Both are relatively inexpensive but uktra reliable. Since we are empty nesting, both are koaded with 3" #4 buckshot.
YMMV

Depends on your frame size and weight. Also who you have living around you like are you in an apartment complex or a single home. I say that because you have to worried about over penetration of large caliber buckshot or slugs. A Remington 870 or Mossberg 500 in 20 ga would be my first choice. 2 3/4 inch #3 buck will be a good choice. Or 3 inch in #2 buck. Make sure it has a good recoil pad. Practice with it too on man sized paper targets so you can see what the pattern looks like. Good luck.
