I like the 165 grain Gold Dots. They are amazingly accurate & reliable in my Glock 23, and recommended by Massad Ayoob...that's a ringing endorsement as far as I am concerned. I've never used the 180's before.
I carry 155 gr. Federal hydra-shok in my 40. If you look at the stopping power charts on handloads.com ...... it rates pretty dang high for 1 shot stops ........... and it's usually readily available locally.
I carry a 1911A1 in .45 ACP for self-defence. So, my comments are irrelevant and totally worthless. I just like to shoot, so I buy the cheapest stuff available from Wal-Mart. That didn't help much, did it?
I have shot the WWB FMJ 165 & 180 for target, have a few hundred rds of the WIN BEB (Brass Enclosed Base) WinCleans in 180, no lead is exposed to gun. For SD I carry WIN PDX1 180 gr. All of these have proven accurate and the FMJ stuff is cheap for blastin' lots of rounds. I'm replacing the FMJs as I shoot it up with the BEBs for the lead issue when indoors. Costs a little more but it has it's benefits.
