marital arts is fine
if you want practical application for self-defense up to effective offensive combat learn all 3 to cover your bases
>wrestling (sambo,greco roman,judo,etc)>striking (muay thai,kick boxing)>melee weapons (kali)are the fastest & most time efficient disciplines
stay away from gimicky bullshit like krav maga especially from former professional soldiers teaching them
the most you get out of those is the mental aspect of merciless attacking but practically speaking you won't be able to apply them properly like they never did since they used guns to kill people all their career.
stick to the basics and master them
don't practice advanced specific techniques for specific scenarios that will never happen
if you master the basics the "advanced techniques" for those specific scenarios will come out on their own.
since that's how those techniques were developed in the first place.
but waiting & wasting your time practicing for specific scenarios is a waste of time and will get you killed trying to manifest them instead of just being practical and going with the simplest solution.
most people who's never been in a fight never takes into consideration the effects of adrenalin and it's debilitating effects if you're not used to it.
t. been practicing martial arts for over 3 decades
PS: I don't even like Glocks
