This has me interested in 10mm again but looks memey
And I've heard it has jamming and over penetration issues.

Are those just memes?

It's fake: If you look at the text of the 10mm result, you can see that it's been made up of cut and pasted bits of the other text, probably because the creator couldn't find the original font it used. Also the nuclear mushroom cloud edited in :\

Pic related is the real chart. 10mm wasn't tested.

Ye, I'm kinda drunk desu
Damn, got bamboozled by a meme almost

Any 10mm pistol recs?

>34134314
Any recs for 10mm around $500?

I have a 9mm, .45 acp, and 10mm.
I guess I'll get a .40 in the future since a lot of .40 guns are being dropped like a sack of potatoes everywhere at cheap prices.

>>34134360
How do you feel about 10mm?

Reliable?
Would you carry it daily?

>>34134387
Not that guy, but I carry glock 29 and it's been great so far. Make absolutely sure that you're comfortable with shooting defensive loads as they can be uncomfortable to some. Another factor is price and availability, if you can only get it by ordering online I'd stay away tbqh.

>>34134387
I have a glock 20 with a 20# recoil spring.
The recoil isn't really sharp, but it is pronounced and more of a deep shove.

>>34134394
Yeah, cost and availability concern me a little. Mostly availability.

I like 9mm for those reasons, and modem 9mm is great, but I wouldn't mind something more powerful

>>34134408
Interesting

I might have to test one of those at a local range that pretty much has everything. If I can deal with the recoil, I might pick one up, as long as cost and availability aren't too much of a pain. A "deep shove" doesn't sound bad, or too "snappy" per se

>>34134301
Thats a nuke photoshopped in hoss

>>34134431
This is why drunk is degenerate

It gets U almost bamboozle

My questions are still serious though

>Thinking about getting a Glock 40 so I can mess around with 10mm, .40 and get a conversion barrel to play with .357 Sig. Basically getting 3 guns in one package.

Good idea?

>>34134227
I carry SR40C, SR9C & LCP2
On the fence about a carry 45
No sense in a carry 10

>>34134227
.40 is better than .45 in every way

>>34134517
Wait...what?

Again, kinda drunk, on top of being fucking exhausted from a long week. Explain.

>>34134538
How So? And how does 10mm compare to .40?

>>34134530
Elaborate? Is 10mm just a silly round?

>>34134592
>? Is 10mm just a silly round?
no
10mm is the future and too many fudds dont want to switch from .45

>>34134583

10mm Glock pistols can fire 10mm and .40 without any problems. You can use a conversion barrel for a 10mm Glock to fire .357 Sig safely as well.

>>34134596
Thank you for the honesty, anon

Is 10mm the "new 9mm" ?
Or the "new .45" ?

Or both? Or better?

>>34134626
That sounds nice
I've always loved .357

So a GLOCK 40 PROBLEM SOLVER would be a good investment?

>>34134227
The only real advantage of .40 is that they command lower prices on the used market than their 9 or .45 counterparts.

First handgun was a Glock 23 police trade in I got for like 300 USD.

>>34134583
>Kind of drunk
>>34134608

>>34134673
I might look for one on the used market at some point then

Seems like it might be better to go with .45 or 10mm if I'm looking for something "more" than a 9mm though

I like the .41AE but short lived+ availability +guns that even shoot it =lmao

>>34134682

>>34134227
Modern 9mm has had a shit ton of work put into it. If you're using a modern gun that can handle +P, carry +P and you'll be fine.

Granted, this is in regards to defending yourself from redguards and meth vampires, if you live in bear country or something I'd probably carry a 3" 357 revolver.

>>34134227
its the best commonly available handgun round for self defense against humans after taking every consideration into account

>>34134723
only if you don't know anything, or think about it too hard. but don't trust me, lets ask the FBI.

>>34134723
That would actually be 357 magnum. It has a long proven record of stopping niggers and statistically (FBI) amongst the highest % of one shot stopping an assailant.

why does everyone hate 10mm

>>34135016
Poorfags hate everything they can't afford

>>34134313
This makes 357 sig more tempting

>>34134632
It will result in a damage in-between 9mm and .45, but that's not much difference anyway.

It has super-flat trajectory though and this is a huge difference especially as range increases.

>>34135016
Because the only guns I find chambered in it are G20/29s and $1500 Dan Wesson 1911s. Maybe when there are more manufacturers making them.

.40 objectively outperforms 9mm and 45acp. 9mm has slightly more capacity and slightly less recoil, and costs less. 45 has no real advantages over the other two now unless "bigger hole bra" is a legitimate argument to you. So don't waste your time on a new .45 unless you want a 1911 or a mk23 or something specifically made for 45. Every other round mentioned is good but also more expensive and heavier recoiling than the 40, and your pistol selection goes down dramatically unless you choose 357magnum.
And that's all I have to say about that.

>>34134538
.50BMG is better than 7.62x51 in every way

>>34134721
>>34134927
People like these guys recommending 357 magnum revolvers over 10mm are leaving out some details. A "compact" 10mm such as the G29 outperforms a 4" 357 mag and has more capacity. The "one shot stop" that the police were reporting was a 125g bullet going about 1450fps from a 4" revolver. G29 can do the same fps with a bigger bullet. Mad bros?

>>34134248
Fake news

>>34135588
What's the minimum barrel length need for non-underloaded 10mm? I know .357 sig really needs a 4" barrel to take advantage of that extra powder.

>>34134353
>Any 10mm pistol recs?
If you're interested in 10mm, the G20 is the only real answer these days.

>>34134632
10mm is basically light-loaded .357mag rimless. The hot stuff has been used for bear and moose defense.

>>34134301
Every thing about 10mm is memes.

>>34135829
> 10mm is light loaded .357
> 10mm pushes a 180gr bullet 100fps faster than .357 mag
> Also do it with 20% less powder ( but that's not as comparable since they use different burn rates)

What am I missing here?

>>34134227

40 caliber is in total decline

do internet search for - 40 caliber demise or decline

used gun stores have lots of 40s for sale

FBI switched back to 9m why ? because with modern ammo yes 9 = 40 = 45

>What's /k/'s opinion on .40?

It's pretty divided around here and seems to get a lot of hate. People who like shooting smaller calibers like the 9mm say like to say that the there is no obvious ballistic advantage. People that shoot larger calibers like the .45 like to say that it's too weak.

Personally, I think the 9mm is more than enough for personal defense, but if you're looking for a bit more power while still being a practical cartridge, the .40 is definitely worth looking into. Typical FMJ loads are more powerful than 9mm and nearly as strong as .45, but offer more velocity and capacity than the .45. If hollow points are your thing, .40 JHP have good, reliable expansion and mass retention.

If you want to learn more about the differences between 9mm and .40, you can check out this 22min video of a guy running several backyard experiments with both different 9mm and .40 rounds. It's not 100% scientific, but gives you the general idea of what each round has to offer:

https://www.youtube.com/watch?v=LTTDgZZZFa0

>>34135943
>what each round has to offer

Inferior penetration and a smaller hole than .45

>>34135617
5" going by Ballistics by the Inch. It seems to me that the "ideal" barrel length for a pistol is the length after which you get serious diminishing returns, minus one inch. The min-max 9mm and .357 SIG barrel is 5" so people like 4". The min-max 10mm and .45 ACP barrel is 6", so 5" is the minimum.

40 is too much of a snappy round due to it being loaded hot. Harder to get your follow up shots and can generally be harder to maintain accuracy. Even ballistically, there won't be much difference in tissue damage. So I'll take 9 or 45 all day due to ease of follow up shots and accuracy.

>>34135588
I didn't recommend 357 mag revolver over anything, I made no recomnendations at all. The FBI publushed statistics on % of one shot stops show 357mag to have a very high %. Do with that information what you will.

That is for the people saying a carry-size 357mag as king. G29 with 3.6 inch barrel will push 135g at 1500+ with 10+1 capacity. I have a G29 and carry Underwood 180g hollow point

.40 seems to be an all around good choice for basically the reasons mentioned PLUS the fact that when talking carbines .40 is the better option. .40 and 9mm are supersonic (faster than sound) so they outperform .45 in carbines on distance. .40 also outperforms 9mm on distance shots in carbines because its a bigger round.

the reason i chose a .40 handgun is because when combined with a carbine the .40 outperforms the .45 and 9mm. therefore i can buy one set of ammo and get the most "bang for my buck" (pun inteneded) with a handgun/carbine combo

im no expert but I believe the FBI made the switch because there was not a material difference between the 9mm and .40 BESIDES the fact that the .40 has a long history of reliability; we will see if they end up switching back. Plus, the FBI buys a shit ton of ammo so the cost savings in a 9mm v .40 is of a big concern for them while for an individual you should pay more for the larger round for the battle tested .40 (in american law enforcement that is)

>>34135895
>FBI switched back to 9m why ? because with modern ammo yes 9 = 40 = 45

Did you actually read the report? Because that's not why they switched.

>>34136806
You can easily get subsonic .40 by going up to 180gr rounds. 165 is usually right on the edge based on manufacturer and 155's are normally supersonic. It's another reason the "45acp because silencers" argument is pointless.

>>34137095
For those interested, shortest summary I could find from https://loadoutroom.com/12077/fbi-going-9mm-comes-science/

> Executive Summary of Justification for Law Enforcement Partners

> 9mm Luger now offers select projectiles which are, under identical testing conditions, I outperforming most of the premium line .40 S&W and .45 Auto projectiles tested by the FBI

> 9mm Luger offers higher magazine capacities, less recoil, lower cost (both in ammunition and wear on the weapons) and higher functional reliability rates (in FBI weapons)

> The majority of FBI shooters are both FASTER in shot strings fired and more ACCURATE with shooting a 9mm Luger vs shooting a .40 S&W (similar sized weapons)

> There is little to no noticeable difference in the wound tracks between premium line law Auto enforcement projectiles from 9mm Luger through the .45 Auto

>>34134227
.40 is more powerful than .45 It is better for barrier penetration and it has more capacity and can be had in a gun that is essentially a 9mm frame.

If you go .40 get a gun designed for it.

>>34135895
they switched because its easier to shoot and requires less training, not because 9mm is better or equal to 40 or 45. its because 9mm is "good enough" and passes their minimum requirements

>>34137150

You mean the agency that picks subpar calibers because women and limpwristed bean counters can't shoot? I think I will make a decision for whats best for me, and not an organization that has to account for pussies fresh out of college.

>>34136017
Actually .40 penetrates people and barriers better than .45.

>>34137173
Did you call them bean counters back in '86 when they pushed for the .40 S&W?

>>34137167
Did they shoot through car parts or office furniture during their testing? we all know .40 does better in those conditions.

>>34137202
Wasn't alive then, but that is exactly why they under loaded 10mm.

FBI is getting cucked by people who will always suck no matter what caliber they have. I choose not to let that happen to me.

>>34137213
Not that I can tell. If there's barrier testing involved, they did not indicate it.

Hornady Critical Duty shows marginally better pen on both 9mm and 9mm +p on auto glass and steel though, compared to .40 S&W. .5" isn't worth switching if was already trained up on the .40.

No idea about Federal HST or Gold Dot LE loads because I can't find their damn gel tests.

Lol, this is because the 9mm didn't expand. It also lost a lot of mass as well.

>>34134227
>opinion on .40?
Im a HUGE 10mm fag, That being said, Id go with 9mm 9, 40, 45 do not differ much to be worth worrying about. When I was starting out, I was autistic about 10s. And if you are not going to carry something big enough to drop a wild boar with one shot, carry what you can put more rounds on target faster.

>>34137223
>that is exactly why they under loaded 10mm
Exactly, first they started with what we call 10mm FBI loads, under power rounds that produces as little energy as current 40 or worse federal had one at (424ftlbs) compared to original Norma loads (638ftlbs)

The ideas was to keep up with a 41 magnum power, not download it to 45 specs

>>34137630
.40 80% to 9mm 70% for auto glass
.40 99% to 9mm 99% for steel

I don't put much stock in expanding pistol ammo outside of making sure it stays in the guy, but that's me.

That being said if you're trained on .40 and windshields are a thing you'll be dealing with, along with bullet diameter, got to go with .40 then.
