BTW - Thanks for the correction. Speer Gold Dots. I think I had them confused with Golden Sabers. Obviously not what I used.
I looked at the information for RBCD and followed the link posted. 90gr .45 ACP rounds? Wow, talk about buying into the high velocity school of thought. I think at some point you're going too light and what you gain in speed you lose from mass. Remember that energy is about mass AND velocity.
What people really need to remember is that handguns suck. They are not ideal weapons but often the one you have. Like I said originally, you really are only going to see marginal improvement. There is only so much you can do with a 9mm bullet. Same with .45 ACP. I'd trust my life to either one of them but if I KNEW I was going into combat neither one are my first choice either.
