I'm considering buying a Glock 30, but I'm a little concerned about penetration from the shorter barrel. I'm sure I could go with a lighter bullet, and improve it somewhat, but then I feel like I'd lose too much energy. What I'd really like to find is a 185-200 gr. +P+ JHP that's known for reliable expansion, but not the "pancake" kind. I like expansion that leaves sheer edges on the bullet, like Barnes' copper X bullets tend to have. Does anyone know of a round like that? I'll cave and go with a more conventional hollowpoint, if need be, but I'd really like to find something that opens up in a little more jagged of a pattern.
