10mm

Extreme versatility. You can load hot .40 S&W for plinking or even self defense, all the way up to bearfucker 9000 rounds. .40 S&W was done simply for gun companies to sell guns in 9mm frames.

No, buy something in .45 Super or .460 Rowland which are superior calibers.

No, the firing pin is just fine, it's just that the round is headspaced off the extractor, and not the chamber.

How do you find an original HK in america?

Interesting, how convenient

And you're one barrel swap away from 9x25 Dillon

Both 10mm and .40 headspace off the case head, in a 10mm chamber a .40 will shoot just fine, even accuracy won't be affected. But caution is advised, make sure your extractor is in good condition, and be sure to clean the chamber after, think steel case in a AR15, the 1mm of chamber will get dirty and cause 10mm rounds to "stick" in the chamber.

Fucking zoomers, day of the SAM when?

SAM?
steel case doesn't make an AR chamber sticky dumbass, this has been covered before

No. It's too expensive. Just use 9mm or .45 ACP.

>doesn't know what a SAM is
Holy fucking shit newfag, lurk fucking more.
>steel
Not because of any lacquer or other bullshit, it's because steel doesn't expand like brass does, and due to this there is leakage from the case, blowing hot carbon back into the chamber. If you shoot brass immediately after, even after 30 or so rounds of steel, you'll often have failures to extract or eject, the worst case (heh) scenario would be a sheared rim. The brass expands to seal the chamber, and the carbon sticks to the brass, acting like a glue.

[citation needed]

bringing up the problem that firing .40 out of a 10mm is murder on the extractor and ejector.

I don't recommend doing it. just buy the cheapest 10mm you can find.

I've been on Jow Forums longer than you have and never heard "SAM" before.

Dumbass

Its FUN to plink with though

1 shot of 10mm is as fun as 4 shots of 9mm

Glock 40 master race

You have bullet weights that go from 60 to 230 grains, with corresponding velocities of 2600 fps to 1100 fps.

This massive amount of variation means that you can find a load for almost anything youd want to do with a handgun.

For self defense against typical dindus theres a plethora of 155 to 200 grain hollowpoints.

Another area where 10mm shines is handgun hunting.

For Small game: 10mm is the only autoloading pistol round that I can think of which has bonafide varmint grenade rounds (liberty civil defense 60 grain rounds). 135 grain hollowpoints would be good for coyotes and the like.

Medium game: Heavier bonded soft points and hollowpoints in the 165-200 grain range make excellent deer slaying rounds. Theres lots of good solid copper options too, like the extreme hunter or penetrator, if you dont feel like eating lead.

Large game: Many, many companies load hardcast lead rounds in the 220 grain range, amongst the hotter loaded rounds you can expect 6+ feet of tissue penetration. While I'd reserve hunting large game for a big bore rifles, there have been many documented african hunts where a hunter used 10mm to kill everything from large warthogs, to waterbuffalo, black bear, and even coastal brown bear. It has the penetration needed for the job. 10mm lehigh extreme penetrators dont have the penetration of hardcast lead but they still go in a little under 3 feet and open up an inch and a half wide permanent cavity.

Additionally, The magnum power and large case capacity of 10mm means that certain projectiles which wouldnt be effective in a lesser autoloading caliber are viable.

Examples include all copper projectiles (like lehigh extreme penetrators, solid copper hollowpoints, etc), which need more case volume as a result of being far less dense then lead bullets. For example, .40 sw 140 grain extreme penetrators must be loaded very cold due to pressure concerns from the lack of case space.

Another example is Superfast projectiles, such as liberty civil defense rounds, extreme defenders, etc. Due to reaching 2000+ fps the temporary cavities of these rounds are actually somewhat permanent, tearing flesh instead of allowing it to snap back into shape.

Glaser safety slugs and other frangible rounds become viable in terms of penetration and total wound creation when you impart them with 700-800 ft lbs of energy, while they still wont go through much dry wall or nearly any steel or wood.

Hell even rip ammo in its 10mm form gets 12 inches of penetration and becomes a lethal (if laughable) option.

Btw, You have 7+ 10mm options that will blow through level 3a body armor. I tested some 100 grain extreme defenders by underwood, and some 60 grain liberty civil defense rounds. Both blew straight through and completely destroyed several water jugs on the other side.

.45 super isnt even real, its an esoteric wildcat for old fudds that tries and fails to emulate 10mm. Its literally made by like 2 ammo loaders, who wank off its power by using 6 inch longslide test guns, and it's still shit compared to 10mm from a number perspective

You have no choice in ammo variety, all you get are solid copper / lead projectiles in the 185-255 grain range (with a single 120 grain lehigh bullet that tumbles instead of properly doing its job because it's too short youtu.be/jhv0LbhNigk) .45 super hollowpoints use projectiles meant for normal .45 acp speeds, which means they will frag themselves instead of reliably expanding.

Nobody makes guns in .45 super, and all of your 1911, hk, and glock conversions are going to shoot themselves apart.

Its 45 acp +p+, but people like to larp as if it's some incredible 10mm killer because it can throw bullets that are 25 grains heavier (and 200 fps slower).

The one thing it has over a caliber like 10mm is diameter, but this has the direct effect lowering your capacity, and making your guns big, which equals out this advantage somewhat. 10mm has some loads that can expand to an inch if that's what you want.

.460 rowland is 45 super +p, with the downside of now needing a whole new gun.

450 SMC or gtfo

pistol stopping power is a myth, shot placement is key, 9mm is king, 10mm is meme

I shoot steel case when training and brass in competitions for improved accuracy and I have never noticed any sticking problems in my AR.
Carbon is a dry lubricant and many delayed blowback rifles use fluted chambers to aid in extraction.

I could believe this. I shot a shit ton of .380 in my 92FS and when I started shooting it like normal, I'd have about 1 in 40 rounds fail to extract because it was stuck in the chamber. I cleaned it afterwards and it has been good to go

Penetration and expansion are not memes, especially against body armor large animals

If the grizzlies are now wearing armor I think we're all boned.

Good thing I have a Glock 40 then which has 10mm ft. lbs. with 9mm capacity, you absolute manlet.

>which has 10mm ft. lbs.
noguns detected.

I meant to say body armor / large animals

10mm would still be a usable option against a bear wearing 3a armor.

Baste

Keep crying, manlet.

>Get the poly Witness instead
It feels like holding on to a wet noodle when you fire it. The poly ones actually are garbage.

that is a funny way of saying 9x25

>If the grizzlies are now wearing armor I think we're all boned.

We need something to stop those armored bears from raping our churches and burning our women.

>9x25

>Is it worth it?

>Best 10mm pistols?
Glock 40. Haven't tried SIG 220 yet.
>Mp5 10mm clone?
I'm sure they're out there. I like Vectors more.
>Is it too hard to find?
It's on Luckygunner. If it's at your LGS, pick some up.

9x25 - 147gr; 6" 1,495 fps - 730 ft lbs. This is claimed by DoubleTap Ammunition.
.357 Magnum - 140gr; 6" 1580 fps - 775 ft lbs. This is from Ballistics by the Inch (BBTI).
10mm - 180gr; 6" 1428 FPS - 814 ft lbs - BBTI.

It's an obscure wildcat cartridge, but I wouldn't call it shitty because it's almost like having 15 rounds of .357 Magnum. Almost.

What's the cheapest gun in 10mm that won't blow itself apart?

One of the derringers probably

>ejector
How? That doesn't even make any sense.

9x25 is kinda just worse then 10mm

It's a good meme for replicating rifle performance from a handgun I guess

10mm MP5s have a bolt hold open device, which I think is pretty cool.

10mm tops out at 975 ft lbs, .357 tops out at ~900 foot lbs

10mm is more powerful and more versatile

>9x25 - 147gr; 6" 1,495 fps - 730 ft lbs. This is claimed by DoubleTap Ammunition.
This is an advertiser's claim, not a real source, for that matter doubletap numbers are infamous for being "optimistic". Googling around shows most people reporting around 1350fps or so without getting significant pressure signs. For comparison .357 magnum can get 1500fps with a 158gr bullet.
>but I wouldn't call it shitty because it's almost like having 15 rounds of .357 Magnum.
Personally i would because just about any testing i've seen has shown it to have less than 100fps advantage over .357 sig with comparable loads and barrel lengths. That gap in performance is miniscule and not worth the drastic difference in market support and moderate difference in size efficiency.
