Why all this talk of using JHP 9mm on enemies wearing body armor? It seems the expansion and increased surface area would decrease pressure (force/
surface area) and penetration. So that point seems odd to me. To my knowledge, I thought JHP didn't penetrate as well.
Also, as far as penetration goes, how well does .45 ACP penetrate body armor? Sure, it has more force (
mass x acceleration), but I'm wondering whether the force is enough to overcome the larger surface area to penetrate well. It may well be. Does anyone here know?
I understand both sides of the argument on this matter. I've never been in a combat scenario to know how well 9mm vs. .45 ACP perform against real people. I'll leave that decision to someone more knowledgeable on the subject. I think our troops should be armed with good weapons that are capable of getting the job done. If the M9 isn't cutting it, then upgrade. The problem, as someone mentioned, is that sidearms probably don't get much use from the vast majority of armed forces personnel as their rifles are their primary weapons.
I've fired a Beretta 92 FS at the range, and I like its ergonomics, but I was much less accurate with it than with my CZ 75 (similar size & weight). I also plan on buying a .45 ACP at some point in the future. If the army does go back to .45 ACP, maybe the ammo price will come down. For now, I enjoy my 9mm prices.
Also, whoever said the armed forces is paying $700 per M9 is probably grossly overestimating. To fill a contract order that large, there's no way they'd shell out $700 per gun. I'm sure it's more like $200. Otherwise, any number of other guns would have won the contract. Hell, for $700/gun, they probably could have gotten Mark 23 SOCOMs for everyone with a contract that size.
