Training ammo vs Carrying ammo on a p365 conceal carry gun

I’m getting a p365 soon.What 9mm ammo do you guys use to train and what ammo do you use for carrying? And why?I’m a bit lost. Some of the people I’ve talked are crazy for cheap ammo but others only use expensive “federal”’ammo. via /r/CCW http://bit.ly/2W9oyfO
