A crossbow would be better, but that seem like it'd work fine.
1. A gun you have is better than one you don't.
2. A gun you are adept at using is better than one you just have.
>.380
yeah sure that's fine.
>concerned about over penetration and efficacy
looks like you got hollow points which reduces penetration and increases tissue damage. don't waste those on practice shooting though, just get some cheap boolets designated for target shooting.
It'll kill people for sure if that's what you're wondering. Cheap ammo and easy to carry as well.
define "suitable". will a .380 kill a man? yes. is it wise to shoot indoors? no, few guns are. hollowpoints are safer though
find a good range and practice. get some click rounds (not sure what the term is in English but blank rounds you can fire without damaging the firing pin) and practice loading, unloading, safing, unsafing and handling it in general
