10mm 

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.

The Socket.
The thing that's always gone and most commonly used when working on cars such as Hondas

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.
