For a carry gun under 10oz that is notably smaller than all but the most exotic, expensive, lightly built micro-nines and has given me 1,000 rounds of flawless performance, the .380 is great for me. You literally can't see the Ruger LCP in my front jeans pocket. The pocket just bulges out slightly, at it would with a thin wallet.
Would I want .380 in a full-size nightstand pistol? Of course not. But too many people expect unrealistic things out of their carry pistols.
My .380 is powerful enough to cause hurt while I flee. If I do my part, it has enough oomph to put down a threat. That's all it's for.
