380 is my minimal carry round...and only when we can't carry a more powerful alternative.
We both have Ruger LCP and wouldn't part with them for any reason. They're ammo sensitive but after determining what they like ... Haven't had a single malf. They're tiny and can be concealed easily.
I also love my LCP when I am in shorts and a T-shirt.
I carry my LCP with ball only but have been thinking about trying the new copper HP rounds in it as they expand and penetrate well.
