I've done a search, but couldn't find a thorough discussion on this. This surprises me, since I would expect that it's not a new question. So...if I've missed the relevant thread(s), please direct me...thanks. Question: What is the recommended/preferred 9mm ammo for HD? I would expect a JHP, but I've seen all sorts of products discussed: Speer Gold Dot, Hornady Critical Defense, Golden Saber, etc. with different loads, velocity, etc. Is there a compliled list/review of these (and other) products? With comparative data, etc. BTW, yes indeed, I am a (retired) engineer! Thanks in advance for the good advice! Wanna kill these ads? We can help!
