I want to hear opinions on what I should use for home defense on my particular case.

To the mods, sorry if this doesn’t fit the sub, feel free to delete.

For starters, over penetration is not a worry because of my solid cinder block and concrete walls, plus the angles that I would be shooting at my intruders are perfectly not in line with any family members or neighbors. So that is a non issue.

The side comes when looking at my country’s gun laws. We have a limit on magazine capacity. Rifle mags can NOT fit more than 10 rounds (so a rifle would be 10 1), a handgun mag can NOT have more than 17 rounds (thus 17 1) and a shotgun is unrestricted on capacity.

Also to keep in mind, there are no restrictions as for barrel length like in the US, there’s no legal categorization as an SBR or a pistol or whatever.

There are no kids in my house and no kids come to my house since all family members are at least 16 years old, still they don’t enter my room. So I can have a rifle or shotgun staged.

There are three occupants in my house, including myself. Of these three, only I I’m/would be armed and willing to use a gun in a home defense scenario.

We have security cameras and an alarm system, plus since we live in Latin America, tall walls, barbed wire and no exposed windows to the outside. To enter my two story house, there has to be a funnel which is my garage door.

Taking all of this into account, what would be your go to firearm to defend yourself and your family? I am very torn at the idea of power vs capacity and multiple assailants. Sorry if this is too long.
