I've found the 380 with Hornady critical defense ammo to be perfectly adequate with warm weather clothing that's the norm for the South East with regards to penetration and wound channel opening. But it doesn't take very many layers of clothing to go from adequate to insufficient. So I'm cooler weather where sweatshirts, coats and multi layers are the norm I swap to a hard cast to obtain as much penetration as possible in hopes of breaking skeletal elements or reaching a vital organ. Plus, I carry this pistol daily as a backup even when hunting. I've used it a few times to finish off deer that I was tracking for others and a few pigs.Honest question as it’s the second time I see this, and have an LCP Max. Why the warm weather carry ammo and then cold weather carry ammo?
