The never to be resolved argument, 9mm vs .45 ACP. Arm chair wannabes to real life ninjas will weigh in with their opinions, some unfounded, but some not.
The one thing that I have expertise in is slinging lead down range. After much research, empirical and real life, I have come to believe that the .45 ACP is what I want on my tool belt when the SHTF. Yes, I also own 9mm and .380 firearms, and I’ve carried 40s and 10s, but my .45 ACP is my favorite.
I know that many Navy SEALS favor the 9mm, but I believe it is for reasons other than ballistic superiority. For one, the 9mm is a NATO cartridge and can be found most anywhere in the world. Also, their theory is the .45 ACP is inadequate in combat because combat adrenaline present in many Tangos requires more rounds downrange than the .45 ACP offers. The presumption is it takes 4 rounds of pistol ammo to take down an aggressive combatant. But wait, my GLOCK Model 20 in .45 ACP with magazine extension carries 15+1. My, my … isn’t that a horse of a different color.
But, to demonstrate how theory compares to reality, I refer you the Moro Rebellion (1899–1913). Moro Muslim Juramentados in suicide attacks continued to charge against American soldiers even after being shot. Panglima Hassan in the Hassan uprising was shot dozens of times before his jihad was stopped. As a result, Americans elected to phase out revolvers with .38 caliber ammunition in favor of .45 ACP to continue their fight against the Moros. Yes, I know a 9mm is not a .38 SPEC, but it is also not a .45 ACP.
As the article states, if the modern and superior hollow point ammunition everyone brags about doesn’t expand, I do have a .45 ACP hardball impacting downrange. Finally, what would you rather get run over by, a high-performance muscle car doing 130mph, or a fully loaded train doing 60mph? Actually, neither one … and that’s the real point to be made. Shoot until the bad guy stops, whether that’s with a 9mm or .45ACP, it doesn’t matter.
