What made you decide on .380? Instead of 9mm, or a .45 acp with a light hp load?
A lot of disparaging the .380 on some of the 1911/Sig Sauer forums. “Junk caliber” is the most commonly-used term, but no one seems to explain *why*.
I’ve never owned or shot one, so I have no experience with it.
It’s difficult to get both good penetration and expansion with any .380 cartridge. Especially if the person is wearing heavy clothing.
