find a real flaw

There isn't one, it's that 9mm is cheaper and just as effective whilst having more capacity.

>>32658738
This. No point in getting .40 when +P 9mm exists

>>32656832
more recoil and less capacity than 9mm without the power gains of .45 acp

>>32656832

It's a pistol round, and all pistol rounds are underpowered garbage.

>>32656832

Pistols should be in .45acp or 9mm. The .40 is a stupid middle ground that is not as good as either of them. It also is hella snappy and sucks.

Most .40acp guns beat the shit out of themselves over time as they were almost all designed in 9mm and adapted to .40.

You sound like a little fairy girly man.

It's a bit short
And a bit weak

>>32656832
its a compromise and not an original design from a single author, so its automatically garbage.

Why some people prefer .40S&W:
It does everything that the other calibers do without any of the drawbacks.

>>32659538
I don't understand blue checkmarks

>>32659538

Isn't 45 out of a short barrel pretty shit for barrier penetration? And 9mm is actually better? If I was carrying .45 I would want a gun that could handle 45 super.

There's no reason for it when I already own a 10mm.

>>32659558
Your problem, not mine.
>>32659597
Heavy projectiles count a lot more than a few hundred fps of velocity.

>>32659615

Do you have some info on 9mm hollowpoints' ability to penetrate auto-glass/car doors? Getting a carry gun soon and don't want to buy something that's garbage.

>>32659558
It means "not actually, but were pretending like it passes".

>>32659645
More momentum = more penetration. Modern hollow points have made 9mm defensive loads better, but they have made all other calibers better too.

>>32659597
>>32659615
Lighter faster projectiles have a slight edge in hard barrier penetration(assuming they hit it head on and not at an angle) while heavier projectiles have the edge in soft barrier penetration.

>>32658851
Derp.

>>32656832
More expensive than 9mm, decreases capacity without the performance gains to justify it. Not as bad as .45, but if you're going to sacrifice all that capacity you might as well carry a 10mm Auto and get some decent performance for it.

lmao I'm sure another 9mm shortage will come soon

>>32658851
Not all of em. 10mm/357 magnum (when loaded to their maximum potential) and higher = significantly more effective than other handguns. When you can effectively hunt deer with the firearm, it's significantly more effective than other handgun rounds.

>>32656832
We could have had ubiquitous 10mm instead. Thanks for nothing FBI.

>>32661879
Having lived through the last one I am sort of considering buying a .40 desu. I honestly see no other benefit.

>>32662321
Not the FBI's fault that there wasn't enough public interest for 10mm.

>>32662413
If the FBI adopted production would have ramped up and price would have dropped, especially if other agencies followed suit. There might have been more interest at a lower price point.

>>32662448

For what reason do you believe that it was the FBI's job to promote the 10mm?

All the FBI did was adapt a lightly-loaded 10mm with a smaller casing for their own use. They could give fuck all what other shooters were doing. It just so happened that other LEOs and private citizens tried the new cartridge and genuinely liked it which is why the .40 is so ubiquitous today. There never anything stopping other shooters from using 10mm. The majority simply chose not to support it and manufacturers responded in kind.

>>32656832
The flaw is you like .40

>>32662964
Its not, this is just a general overview of market forces surrounding government acquisitions. I am just bitter because I want to live in an even more cyber punk future than we do now.

>>32658746
sTANDARD .40 HITS HARDER AND PENETRATES BETTER THOUGH.

it's not metric.

Standard .40 doesn't penetrate very well. Fuck you. Let's go.

>>32658746
I switched from .40 to 9mm for the single reason that it's cheaper to shoot. Otherwise, I'd still be carrying .40.

>>32658738
First post best post

>>32663603
I'm planning on getting the guns I shoot (both full size and compact models) in .40 to carry and keep my current pieces for the range.
