The ideal weapon for home defence is a sawed-off shotgun (easier to carry & use in close quarters) loaded with alternating rounds of birdshot or buckshot and slugs. At home defence distances where the target is 20-25' away at most, birdshot will cause massive surface wounds without over-penetrating and blowing holes through walls, but it won't reliably penetrate deap enough in humans to hit vital organs. It's prefered for cheaply-built condos and non-detached housing where you don't want stray pellets to hit your neighbours. For detached housing, buckshot is prefered, it reliably penetrates to vital organs and has a good one-shot stop rate. The slugs are there in case the bad guys are wearing body armour, if you shoot him with buckshot and he gets back up, he's got a slug waiting for him that'll blow nicely through his armour and put him down.Durandal wrote:As far as home defense goes, do you really want an assault rifle? In close quarters, they're rather cumbersome. Wouldn't a pistol be a better weapon? Or a shotgun?
Pistols are underpowered according to most experts, it's easier to shoot for some people but you trade off a lot of stopping power and you have to aim them more carefully than shotguns. Due to their length, rifles are not recommended for home defence situations, it's too easy for them to get hung up or whatever and using them in tight quarters is a bitch.
