three calibers, 9 mm, 40S, and W 45 ACP. Every gun owner in America has an opinion on which one is best. Most of them are wrong. This video puts all three side by side with the same ammunition, the same gel protocol, and the same data. One winner, two losers. And the result is going to make at least 2/3 of the people watching this uncomfortable.
The 9 mm crowd thinks capacity settles it. The 45 crowd thinks stopping power settles it. And the 40 SNW crowd thinks they found the perfect middle ground. One of those groups is right. The other two have been lied to by an industry that profits from keeping this argument alive. Let’s start with what the GEL actually says when you test all three side by side.
I’m using Federal HST across all three calibers. Same manufacturer, same bullet line, same design philosophy, same FBI barrier protocol. This is as close to a controlled experiment as you can get with factory defensive ammunition. Federal HST 147 grain 9mm penetration just over 15 in expansion 6/10 of an inch weight retention 99%.
Federal HST 180 grain 40S and W penetration just under 15 in expansion 6/10 of an inch. Weight retention 99%. Federal HST 230 grain 45 ACP. Penetration just over 14 1/2 in. Expansion just under 7/10 of an inch. Weight retention nearly 100%. All three inside the FBI’s ideal 14 to 16 in window.
All three expanded reliably. All three retained virtually all their bullet weight. The expansion difference between the 9 mm and the 45 less than a tenth of an inch. The penetration difference half an inch. You could not tell these wound channels apart on an autopsy table. That’s not my opinion. That’s what the medical literature on handgun ballistics has been saying for over a decade.
Terminal performance with modern premium hollow points is clinically indistinguishable across all three service calibers. And yet the industry keeps selling you on the difference because caliber tribalism moves product. A guy who believes his .45 hits harder than your 9 mm buys 45 ammo, 45 magazines, 45 holsters, and a 45 pistol.
The debate isn’t about ballistics. It’s about revenue. But the GE data is only half the story because terminal performance is where these three calibers are the same. Everything else is where they’re different and the differences are brutal. If this is your first time on this channel, subscribe. I’ve done four of these caliber breakdowns and every single one came with verified numbers, not opinions.
What you’re about to hear is going to settle arguments you’ve been having for years. Capacity. A Glock 17 in 9 mm holds 17 rounds. A Glock 22 and 40S and W holds 15. A Glock 21 in 45 holds 13. Same manufacturer, similar frame sizes. Four more rounds in the 9. In a defensive encounter, law enforcement hit rates average between 20 and 30%.
That means out of 13 rounds of 45, you’re statistically landing 3 to four hits. Out of 17 rounds of 9 mm, you’re landing four to five. One extra hit from the same shooting performance, just more opportunities. Recoil. The 40 SNW generates roughly 30% more felt recoil than 9 mm in comparable pistols. And here’s what nobody in the 40 crowd wants to admit.
The 40 doesn’t kick like a 45. It kicks worse. The 45 has a slow rolling push. The 40 has a sharp, snappy bite. It’s faster slide velocity, higher chamber pressure, and a recoil impulse that punishes the wrist instead of pushing the hand. Shooters who’ve run all three backto-back consistently rank the 40 as the least pleasant to shoot.
Not the 45, the 40. That snappy recoil does something else. It wears out pistols faster. Springs, guide rods, frames, all take more stress from 40 SNW pressures than from 9 mm. The Glock 22 has a recommended replacement spring interval shorter than the Glock 17. You’re paying more per round and replacing parts more often for a caliber that performs identically in gel.
Cost 9 mm FMJ runs about 18 to 22 cents per round in bulk as of 2026. 40S and W runs 28 to.35. 45 ACP runs 30 to 40. If you train with 500 rounds a month, that’s the difference between roughly $100 for 9 mm and $200 for 45. Over a year, you’re paying an extra $600 to $1,200 to train with a caliber that puts the same size hole in gel.
And here’s the math that actually matters. That $1,200 you saved shooting 9 mm, that’s another 5,000 rounds of trigger time. 5,000 rounds of practice is worth more than any caliber advantage on Earth. The best defensive cartridge isn’t the one that expands to 7/10 of an inch. It’s the one you can afford to practice with enough to actually hit what you’re aiming at under stress.
Subscribe if you already know where this is going. And if you’re angry, good. That means you’re paying attention. Now, the part where I lose friends, the 40 SNW was created because a single 9mm bullet stopped 1 in short of a suspect’s heart during a gunfight in Miami in 1,986.
The FBI panicked. They wanted a bigger round. They created the 40. Then in 2014, after 28 years, the FBI looked at the modern gel data and switched back to 9mm. The agency that demanded a bigger caliber admitted that bullet technology had solved the problem the bigger caliber was invented for.
The 40 SNW is a solution to a problem that was fixed 20 years ago. It gives you more recoil than nine for the same terminal performance, less capacity than nine in the same frame, higher ammo cost, faster component wear, and in heavy clothing barrier tests, some 40 loads actually overpenetrate because the bullet clogs with denim and fails to expand.
The caliber designed to outperform the 9 mm in the FBI protocol, sometimes performs worse in the exact test it was created to pass. The 45 at least has an identity. It’s the subsonic round that suppresses beautifully. It’s John Browning’s cartridge. >> Rest there. >> It’s 113 years of military history. >> It’s the round your grandfather carried in the Pacific.
The 45 has earned its place even if the gel says it doesn’t hit harder than a nine. Some guns are more than their ballistics. The 40 has none of that. No history, no niche, no identity. It’s 35 years old. It was born from a bureaucratic panic and the bureaucracy that created it already walked away. It’s not the cheapest, not the most available, not the highest capacity, not the softest shooting, and not the hardest hitting, middle of everything, best at nothing.
Now, before I give the verdict, two angles that matter to the people actually watching this. Concealed carry. When you shrink a pistol down to pocket or subcompact size, recoil differences get amplified. A 9 mm in a SIGP 365 or a Shield Plus is manageable. A 40S and W in a subcompact is genuinely unpleasant.
The sharp recoil impulse in a 22oz pistol makes follow-up shots difficult, even for experienced shooters. and the 45 in a subcompact barely exists as a category anymore because manufacturers know the market rejected it. The compact and subcompact concealed carry market belongs to 9 mm and it’s not changing.
If you carry concealed, the caliber question was answered by physics. Smaller gun, lighter gun needs a softer shooting round, 9 mm. Reloading. This is where the 40s SNW and 45 ACP have a legitimate edge that nobody talks about in these comparison videos. 9 mm operates at higher chamber pressures, 35,000 psi versus 21,000 for 45 ACP.
That means 9 mm reloading has a thinner margin for error. The 45 ACP is one of the most forgiving handgun cartridges to reload. low pressure, straightwalled case, widely available components. If you are a reloader who shoots 1,000 rounds a month, the 45’s cost advantage through hand loading is real. You can load 45 ACP for 8 to 10 cents a round versus 12 to 15 cents for 9 mm.
That inverts the factory ammo cost argument completely. The 40 SNW is also reloadable, but it is the most finicky of the three. higher pressure than 45, smaller case volume than 9, and brass life is shorter because of the operating pressures. If your primary reason for considering the 40 is handloading economics, the 45 is a better choice.
So, here’s the verdict. For self-defense, carry, and training, 9 mm. Not because it hits the hardest, because it’s the most shootable, the most affordable to train with, and the most capacity in any given frame size. Terminal performance is identical with premium loads. You will shoot more, flinch less, and carry more rounds than with either alternative.
For suppressed shooting, subsonic applications, and the 911 45 ACP, it does something the other two don’t. It fills a role. It has a reason to exist beyond splitting the difference. For the 40s and W, if you already own one, keep it. It works. The ammunition performs. Don’t sell it because a video told you to.
But if you’re buying your next defensive handgun and you’re choosing between these three, the 40 is the one I can’t build a case for. Not in 2026. Not with the data in front of me. The biggest lie in the gun industry isn’t that one of these calibers is better. It’s that the debate is still worth having. The gel settled it. The FBI settled it.
The agencies settled it. The only people still arguing are the ones who haven’t read the data. And the manufacturers who profit when caliber tribalism stays alive. Drop your caliber in the comments.
