The greatest pistol cartridge ever created; the only practically sized round to ever combine high speed, penetration, accuracy and stopping power. Has the same projectile as the .40S&W, but more powder gives higher performance.
The GLOCK model 20 chambered for the 10mm auto is a perfect 10.

Damn where is my 10mm, fuck it fell down the Engine.
I got the 10mm with my two fingers but it fell down again, it fell somewhere where I can't see it.

Patrick do you really think we left the 10mm inside the engine when assembling it again.
No I don't think so... ow shit you're right the 10mm was on top of a screw head inside the engine, damn my fault...

10mm Auto 

A powerful semi-automatic pistol cartridge introduced in 1984 for the unsuccessful Bren Ten. The cartridge is today quite underrated and rather uncommon, but is used for handgun hunting and self-defense.
A less powerful version of the cartridge was later developed for the FBI; this became known as the now very popular .40 S&W.
Guns chambered for this cartridge include:
Bren Ten, Glock G20, Colt Delta Elite, MP5/10 submachinegun
My uncle just nailed a white-tail deer with his Glock 20 with a 10mm Auto FMJ.

endwarfins

The rush of neurotransmitters and neuropeptides triggered specifically by watching the Seven Dwarfs march home singing "Heigh-Ho" — that particular high of pickaxes, whistling while you work, and communal domestic bliss in a cottage built for men half your height.
I only meant to watch the Heigh-Ho scene for the endwarfins, and then it was two hours later and I'd watched the whole movie.

Endwarfins aren't just a Snow White thing — I get the same hit off the Lollipop Guild in Oz.
