Can someone explain to me why the blowback mechanism of a modern

>>31871035
The pressure behind the bullet that forces it out of the barrel pushes the slide back, ejecting the spent casing and chambering a new round from the magazine.

It doesn't. As soon as the round goes off, the gases push the slide backwards (I'm really over-simplifying this) which ejects the spent cartridge and allows a new round to slide into the chamber.

The bullet travels so fast, it leave before the cartridge has time to move back

You're a "special" underage kind of noguns, aren'cha Champ

You may be getting confused by had animations, but like >>31871083
said the action starts moving immediately.

Even if he is, you don't have to be such a condescending asshole. Teach him or at least point him in the right direction.

OP, the blowback mechanism unlocks and opens only after the bullet has exited the barrel because if it opens while the bullet is still in the barrel, the expanding gasses will go the easy way out, backwards, which means bursting the thin brass casing wall and in worst case scenarios render the gun inoperable.

Inertia, nigger.

... because it's really really fast.

TL;DR: Glocknade

No that's because Glock decided it was a great idea to bore out 9mm chambers to .40 because "cheap lmao" and not reinforce them at all.

The weight of the slide plus the spring retards the slide. So the bullet leaves the barrel faster than the momentum that pushes the slide back. After thst barrel and slide travel back because they have overcome said retarding momentum and the reloading show beguns

it doesn't

bullets are fast

Mass. The ratio of the slide velocity and its mass is equivalent to the ratio of the bullets velocity and mass. Newtons 1st law of motion.

Bullet has low mass, goes fast as hell. Slide has relatively huge mass, goes much slower.
