OK, here’s a question for all you “Mouse Gun”

affectionadoes.
I have two friends that both carry the Ruger LCP 380 even if they are packing a larger caliber gun. One swears by carrying nothing but hollow points and He uses Hornady Critical Defense.
The other who shoots A LOT, 15-20 thousand rounds a year is just the opposite. He says the 380 isn’t really all that powerful (true), and needs all the penetrative power it can get. He shoots nothing but ball ammo through his. Oh and neither Carrie’s a spare Magazine, which I actually find odd. Ever since I started carrying a gun (first as a dispatcher and then a cop) I ALWAYS carried 2 reloads.
So, what do Y’all dogs think? I’m aiming this (no pun intended) at you mainly MB, cause as far as I know you’re the closest thing to a ballistics expert as we got. And what are Y’all’s thoughts on spare mags for it as well.
