I have been use to a .25 for many many years. My reason for the new .380 was more power, same size, that simple.
Besides all the "bad" you read on the .25, I never once felt "under armed" in close situations. I have many old soup cans that looked like major pin cushions, in and out and gone.
So the new .380 I cannot wait to try, being use to the .25 as a pocket rocket, the .380 should be a power house
