Can we all finally agree that .40 Short & Weak is a dead caliber that offers no advantages anymore over other pistol calibers like 9mm?
More money per round for negligible performance increase and less capacity has killed it.
RIP .40S&W!
>>30086099
It's a good round if FMJ is your only choice. I think it'd make sense for the military on those grounds... But for everything else I agree the 9mm is superior.
>>30086099
What?
No.
Plenty of agencies and LEO and civilians use it.
Its not going anywhere.
Its just a intermediary combining the good parts of 9mm and .45
>>30086099
Their flat nose and wider body make them more pleasurable to insert into your anus than 9mm
>>30086114
Weakening the strengths of those 2 calibers only brings out their weaknesses. They need skewed heavily to one end of the spectrum to retain their effectiveness.
>>30086111
>9mm is better
.40 makes a larger hole.
>>30086131
It has better penetration and delivers more energy on target than a 9mm.
And it has better capacity than .45.
Thats why I said it's an intermediary between the two.
All things have strengths and weaknesses. Also that is not logical
>>30086132
as if it matters when it comes to pistol calibers... nigga pls!
>>30086114
FBI has told police to move to 9mm after analyzing thousands of shootings, medical reports, and ammo testings. .40s&w ain't fucking worth it.
>>30086142
Larger diameter means that extra energy is lost.

>>30086114
Well OP, faggots like this one keep others about the round being a good jack of all trades round. So sadly no, the cancer is aggressive, and will keep ruining otherwise fine handguns for the foreseeable future.
>>30086132
I covered that, as an FMJ it makes a bigger hole than a 9mm FMJ. With hollow points there's no difference, sometimes the 9mm can even expand larger. The reason is that the 40 uses a much shorter bullet for its diameter, so it can't expand as dramatically as the 9mm can. You learn something new every day.
>>30086099
I feel like the people that defend 40 sw either forget, or don't know its a compromised 10mm because pussies couldn't handle 10mm recoil. 10mm definitely offers an advantage over 9mm and 45acp in energy and muzzle velocity at the price of significantly greater recoil, 40sw on the other hand is just a castrated 10mm with no real advantage effectively filling a roll that didn't need to be filled.
>>30086142
Incorrect.
Pistol caliber has no influence on energy delivery efficient. Velocity, weight, and bullet design are what matters for energy transfer. Fast, light, expanding bullets deliver energy more efficiently than heavy and slow bullets. This means a 9mm JHP delivers energy more efficiently than any 45acp.
45acp runs at 350ftlbs of energy, 9mm runs at 330-450ftlbs of energy. So 9mm in most cases is a more powerful round if we go by the data.
>>30086288
>filling a roll

>>30086131
Yeah you can use the same argument with 5.56mm or any intermediate round.
Jesus Christ.
Viper u r so dum
>>30086257
A 9mm JHP will never expand larger than an identically designed .40 or .45 JHP.
They are the smaller bullet... They are .38 caliber.

>>30086292
Fast, light, expanding bullets also can't reliably kill or incapacitate through walls, doors, windows, fatties, etc.
FMJ is superior in many ways.
Haven't you seen those xrays of people shot like ten times by police with JHPs?
If it doesn't have enough energy to exit a target, it can not be relied on to penetrate through vitals.
It's that simple.
>>30086288
Buy a .45 and shoot .45 Super. You get identical ballistics to 10mm and the best of both worlds.
>>30086339
Find me a 40 caliber load that expands above .72" while still penetrating past 12". 9mm federal HST 147gr does this effortlessly through almost any medium.
>>30086381
Because fast, light, expanding bullets deliver their energy efficiently. This means they also dump it into any barriers they hit. They can still penetrate well if properly designed.
>>30086362
This is breddy gud. Now that people are moving away from .40 the guns are cheaper. Would make a good back up to hand off to someone or if you need to send in your main gun for refinishing/repairs
hey fortay, go fuck yourself
>>30086362
DAMN!
Police are unloading all the .40 guns. If you're into .40, there's some good deals to be had. However, you will lose in the long run due to the price of ammo.
>>30086405
357 sig is just about perfect ballistically. It does have downfalls though. The concussion and blast is worse than a rifle in some cases, not something you want to touch off indoors. I love the round but I'd be hesitant to use it indoors.
Thats why you go 357 sig. 9mm with 40 cal power.
>>30086381
>Buy a .45 and shoot .45 Super
.45 super makes 10 mm look cheap and bountiful. he's better off with a 9 mm and a 10 mm.
I like .40
Its pretty fucking cheap guys.... Like what the fuck have any of you actually looked at the prices.
I like the .45 but the fact its so inheritly low capacity is upsetting.
Also all the LEO in my area use .40 and about half the people I know with handguns.

9mm is going to go the way of .32 ACP pretty soon.

>expanded diameter is the ultimate predictor of lethality
You're missing one detail. Once a bullet hits a bone or other hard object, it loses a lot of its kinetic energy. Heavier bullets have the momentum to retain their velocity better after breaking through barriers than do lighter bullets.
>>30086579
That's not how momentum works.
That's not how terminal ballistics work either. There's a reason the FBI dropped .40 for 9mm.

I'm guessing that the last time they looked at prices was like 2013 when it was more like $20/box. Then again, 9mm was the same price at that time. I recently bought a case of .40S&W for $220. It really is cheap right now, just $1 more per box than the cheapest comparable 9mm in most cases.
>>30086579
Larger expansion=More tissue cut/displayed=More bleeding. Handguns can only poke holes, so the more bleeding they can cause with that poke, the more effective they will be. They still need to drive deep, and punching through a rib is literally nothing for any service caliber.

Who gives a fuck what the FBI uses? Not too long ago, you fags were ripping on them for using .40S&W. Now you're praising them for their ammo choice. I don't think you have any idea about ballistics yourself, and just parrot what you hear in gun forums.

>>30086631
That's not how lethal hits in a self-defense shooting work. If the plan is to wait for the attacker to bleed out, then you'll be waiting for 5-10 minutes. The plan should instead be to get your bullet to make contact with the CNS and incapacitate the attacker. Heavier bullets help with this. The spinal cord is protected by bones, as is the heart.

If the idea is to let them bleed out or cause soft tissue damage its literally gonna be minute(s) and they could get off quite a few rounds.
You need to hit them somewhere vital (Spine skull or heart)and the simple thing is that larger diameter makes that more likely.

The FBI has already concluded there is no appreciable difference between all the most common carry calibers as far as ballistics go.
>>30086760

The police lied. He was likely wearing armor under the jacket.
>>30086672
Do you think touching the CNS with your finger stops someone? It doesn't. The more damage inflicted to the CNS the faster the stop. It doesn't take 5-10 minutes to bleed out, it takes less than 7 seconds if the shot is placed properly in the chest. With it being likely they will lose consciousness before 7 seconds even passes.

This is how retarded you sound. Do you even understand the kind of law enforcement that the FBI does? They are not the ones patrolling the concrete jungle, relying on their service weapon just to survive the day, I will give you that hint.
>>30086979
You are more than welcome to refute the scientific deconstruction of the different ballistic capacities of any given service caliber in this post >>30086979
>>30086964
Yes, it is because you don't understand the reasons why they switched. You're just repeating what has been regurgitated into your ears through a million gun forums. Also, this: >>30086979. They did "research n shit" when determining that .40S&W was the best too. Guess what, the SAAMI specs for those calibers haven't changed since then.
>>30086099
One advantage of .40 over 9mm (and it's situational) is that sometimes it's available in stores when 9mm isn't. Rare, but it's happened to me a few times.
>>30086928
Your leg to stand on is less than 0.05".
.40 beats 9mm in barrier penetration. Yankee Marshall said so.
>>30086979
>>30087026
>less than 0.05".
Excuse me? A 180 grain bullet has 45% more mass than a 124 grain bullet. Since the velocities are comparable, and momentum is calculated as velocity x mass (increasing linearly as either value increases), that translates to roughly the same percentage increase in momentum.
>>30086979
It's so fucking hilarious to hear the same forumkiddies who blasted the FBI for using .40S&W up to a year ago, now using the FBI as an authoritative source for why 9mm is apparently so great. I am honestly starting to think that they can't even see the irony of it.
When was the last time a carhartt jacket stopped .40?
>checkmate atheists
>>30086099
>dead caliber
The term only applies if manufacturers aren't selling the caliber anymore. Unfortunately for you all the big name manufacturers still offer guns in .40 like S&W, Beretta, Glock, and Sig just to name a few. People need to stop buying the calibers for manufacturers to stop offering them and the fact that they are still making them means that there's still enough interest to keep making guns and ammo in that caliber.

Unless you are using bullets that use the extra energy well, yes. Also the 7.62x39mm M43 PS ball ammunition that Russia used up until they adopted the AK-74 left wounds comparable to .32 ACP due to the bullets icepicking through on shots from most angles.
>>30088321
>Or just use ball ammunition, in which case .380 and .32 ACP both work.
You fail to understand the concept of momentum on a fundamental level.
>>30086099
It's not as good as it should be, but it's still just fine for defensive carry.
Besides, the guns that use it are cheap because of all the trade ins and shit
I shoot .40 more accurately than 9mm. What's wrong with me?
>>30087049
muh .72 expansion in liquid gel muh fugga
>>30088505
It doesn't matter if X ammo has more momentum/sectional density/whatever than Y ammunition when testing shows that Y ammunition has enough. If you want to make arguments otherwise then post proof of .380 and .32 ACP ball ammunition failing to penetrate far enough.
>>30088877
Are you talking about your accuracy when shooting quickly? If so, you likely aren't taking the same amount of time to aim with 9mm that you would with .40 S&W due to various reasons. I noticed it a little after I got a .22 pistol.

Is your .40 more powerful than multiple shotgun rounds?
BTW, I have personally met a kid (about 13) who was shot in the back of the head with a .40. It blew out his eye but he was fine.
Any round can fail to stop, and the difference in rates between a 9mm and a .40 is negligible (and slightly in favor of the 9mm)
>>30089265
Sleep tight puper
>tfw gotta wake up at 6 tomorrow
>>30088877
I'm the same way, and I shoot .45 better than both .40 and 9mm.
I can put 5 rounds of .45 in a smaller target faster than I can put 3 rounds of 9mm, which sucks because I only have 1 gun in .45, but I have over 12 in 9mm. I really want to like 9mm, but I just can't get gud with it.

>Le bird shot can't kill you maymay
Shotguns as a whole outclass any rifle or pistol for lethality, one-shot-stop rate, and average shots to incapacitate.
>>30089354
Certain birdshot loads can't put a hole in an aluminum beer can at 25 yards, let alone kill someone in one shot. Not that I'd want to be shot by one, but given the choice, I'd take it over even a .25acp at that range.
Stop being such an obtuse fucking idiot.
>>30086099
When the FBI moved back to 9mm, that was the first nail in 40S&Ws coffin. Right now the market is fine, but as contracts shift back to bulk 9mm production, less factories will make the 40 round and prices will start to go up.
It's not dead, but it's 10 year decline is starting.
>>30089402
Why are you using birdshot for self defense? Your argument is asinine.
>>30089526
My argument was that the term "shotgun round" is non-discrept and could mean anything from a 10ga 3.5oz slug to a salt load in .410.
The fact that you didn't realize that makes you a fucking obtuse idiot.
>>30089547
And 9mm "could" mean one of those CCI rat shot things you could get. Doesn't change the fact that people have taken multiple 12 gauge hits and kept going.
>>30089547
9mm "could" mean rubber bullets, but only a reddit-tier faggot who wants to win an argument would make that logic leap.
>>30089573
>>30089588
The difference is that cops don't carry less than lethal 9mm, but they do often carry less than lethal 12 ga,
Also, cheap as fuck low brass trap loads are significantly more common than buckshot or slugs.
I'm starting to think you haven't been around guns very long, or you're intentionally being an obtuse fucking idiot.

Its not though, unless you aim only for soft flesh.
They usually have 50-65% of the powder charge. I'd say the average high brass hunting load could probably break bone, but trap loads fuck no unless you suffer from sever osteoporosis. I shoot a lot of shotgun, and theres a reason why a lot of trap ranges don't allow high brass loads.
Also realize that the "pool of data" used for that statement in the aforementioned post was probably taken from police reports, which involves people who no nothing other than "get shotgun go boom and kill the bad guy", they will buy a short shotgun with a cylinder choke and the cheapest shells, which are weak, dirty, pathetic little trap loads that can't dust a clay at 10 feet let alone 30 fucking meters.
>>30089603
"Carry?" less than lethal shotgun rounds? Riot police, I guess, but assuming that the shots they're talking about there are rubber rounds bounced off the ground is just as stupid as assuming they were quail shot being fired at someone across a field.
It's pretty safe to assume that if someone is deliberately trying to kill someone with a shotgun, I.E shooting them multiple times, they probably didn't load rock salt.
It's also pretty reasonable to assume that if they were talking about a specific instance in which someone was shot multiple times with rock salt, they wouldn't bring it up in an article about people surviving insane amounts of gunshot trama.
The assumption that the article is talking about less than lethal rounds or rounds used far outside their effective range is a stupid one to make.
For a specific example, by the way Michael Platt took multiple shotgun hits in addition to his 9mm and .38 special wounds, but ultimately died from internal bleeding caused by a 9mm wound he suffered in the first few moments of fighting.
This goes back to the original point that people survive absurd fucking shit sometimes, and it's not exclusive to 9mm.

Then why do they propel the same amount of shot (1 1/8oz) at the same velocity (1250fps)?
>I'd say the average high brass hunting load could probably break bone
No shit.
>but trap loads fuck no
Average high brass hunting load: 1 1/8oz #7.5 or #6. Average trap load: 1 1/8oz #8 or #7.5. If you wanna get into the "specialty" high brass hunting loads like Prairie Storm that have nickel-plated 5's or copper-plated 4's, sure. But you'd be literally tripling the mass of each pellet. And they're "specialty" for a reason.

>know-nothings who buy bulkpack birdshot for HD
Birdshot will absolutely leave a single 1" hole in someone inside about 30 feet (more than twice the average home defense range) and the shot column, which acts more or less like a single projectile when it's that dense, will achieve >20" of penetration.

Don't have a link right now and don't feel like looking for it tonight, but there was a study a while back and the ribs/spine are consistently equal to a couple inches of ballistics gelatin each across a wide range of velocities.

Momentum increases linearly with mass and velocity. Mass x velocity = momentum. Double one of the values and you'll double the total momentum. It's much easier to increase the mass than it is to increase the velocity. To get a comparable momentum increase as .40S&W offers, with a 124 grain projectile, you'd need to propel it1600 fps, which 9mm Luger's SAAMI specs are not capable of doing.
>>30089247
Yeah, with poor shot placement even 10mm will fail to stop someone. Unless you are talking about moving up to .44 magnum or .460 Rowland where fragmenting ammunition that can make up for poor shot placement becomes possible in a pistol. Life isn't a video game where people have a health bar. Lungs take a long time to deflate and someone with a high pain tolerance has absolutely no reason to stop if you don't shoot them in the spine/brain or something that will cause rapid blood loss such as the heart or major arteries (though that can still take a long time, however long it takes for them to lose just under 1/2 gallon of blood or about 1/3 the blood in their body).

when there's a change like that, somebody gettin their palm greased.

It's not so much that you think you're bullshitting, but more that you fail to understand key concepts yet keep plodding forward with your claims in spite of the fact.

45 does it better.

.45 Super can be shot safely through cast frame RIA 1911s dude.
.45 ACP was underpressue to begin with, .45 Super just gives it a more modern pressure.
i'm going to purchase a .40 S&W pistol this year, and i agree 100%.
the reason i'm doing it is because the rules of the division i want to get involved in require .400 caliber bullets to make Major scoring. i don't like it for any other reason.

Same anon you responded to, not the same anon who mad the original post. What "key concepts" are you talking about exactly?
>>30095382
Why not get a 10mm and become a raging douchebag?
>>30095886
.40 s&w has milder recoil and virtually the same trajectory.

Appeal to faulty authority is a fallacy

penetration of hard barriers doesn't increase linearly with momentum though.
Just use 5.7×28mm :^)
>>30096730
That's a ridiculous claim. There are all sorts of materials that could be considered "hard barriers," from car doors to bones to 2x4's. Ability to penetrate a given material does, however, increase when momentum is increased. I don't know how you'd go about measuring it to claim if the progression is "linear" or not - you'd be trying different bullets and they wouldn't be penetrating, and all of a sudden past a certain value they all start penetrating. It doesn't sound like a very informative statistic.

This, it's a great round.
9mm sized gun with 30% more heft. It's great and you can switch out the barrels with a .357 sig hard cast round from buffalo bore and have an unbelievably great penetrating gun for hiking or whatever.

>Can we all finally agree that .40 Short & Weak is a dead caliber that offers no advantages anymore over other pistol calibers like 9mm?
No.
>>30086117
Indeed.
