It is more powerful

Good meme, original joke, and made me blow air out of my nose.

He really must have wanted to “blow” their minds.

Exactly

mecore:

That's not 9mm. The Glock 23's chambered in .40 S&W. For anybody who knows anything about guns, that will get you laughed at more than having a 5cm.

Whats the difference between mm and .## caliber me confused

1 cl = 0.254 mm

That.

So wut 9mm in caliber?

.38 Caliber. It's the same width, but different lengths of it. There's 9x19 Luger (which is what most people think of when they hear 9mm), 9x18 Makarov (which is my preferred carry), .38 Special, and .380 ACP (which is basically 9mm for babies).
