good info, thanks, I purchased a 9mm from an officer who used it as a back up, he chose Speer Gold Dot ammo, this was a while back before the current generation of rounds and Speer Gold Dot was well regarded for expanding well under various situations.
I found some PPU ammo at Cabela's once, that was 147gr HP ammo, for just under $20 for a 50 round box. I bought a couple of them. I'm sure those HP's are not as good as the "premium" rounds like Gold Dot, or Fed HST's, but, for me, they would be more than adequate. Certainly not "the best", but way better than FMJ ammo.
