I don't worry about over penetration too much in .380, even tho I realize it could be a potential risk. Missing shots altogether is much more likely and way worst, but anyways, what do you think of the terminal ballistics and the ability of this specific round in the Glock 42, as far as stopping a threat/self defense? Thanks. Edit: By the way, the base diameter is 0.356" and the meplat (flat nose) is roughly 0.25". So the actual cut hole size might be 0.25" inches diameter, while the rest of the bullet theoretically just pushes/slides through tissue. I feel that 2-3 rounds to chest and vast majority of people are in bad shape, in my opinion.
