1911 Firing Animation

[65Mustang]

I posted this in Non-Glock Firearms but thought I'd post it here too. I'm not sure if its been posted before, but its too cool not to share. Check it out: Click Here (http://www.m1911.org/loader.swf)

Been posted before but it's always nice to see it. That is a cool animation.

Today is the first time I ever noticed the "split" option which shows cutaways

[OSSI]

Its my screen saver:)

It's interesting that the slide waits until the bullet exits the barrel before starting it's cycle, iff'en the animation is correct.
I seem to recall reading that it does.
Can anybody tell me why?

[65Mustang]

This is purely a guess... but my answer would be because the bullet is traveling at such a high velocity, it exits the barrel before the slide has a chance to react. I don't think its planned or meant to happen in any order, more or less just the laws of physics. Course I could be wrong...:cool:

So... how does one say something like that? A shockwave file, that is...

You can download it from the stiguns site as screen saver

A .45 ACP cartridge at standard velocity, about 850 fps, exits the 5" barrel in about .5 milliseconds, so the mass of the slide and the force of the recoil spring will retard movement of the slide to the rear for just a bit. Perhaps the biggest factor is that the brass case will swell due to the internal pressure and the slide cannot pull it out of the chamber until it cools a bit, again, far longer than it takes for the bullet to traverse the barrel and exit.

The slides are also engineered to have sufficient mass to delay movement until the pressure drops to safe levels.

Its my screen saver too.

This is all a good thing. Once the slide starts moving rearward, the barrel starts tilting. You want the bullet to go high?

;f

Request for a sticky, please.

I orginally posted this in Non-Glock Firearms as well; here is the link to that thread. Some memebers have posted links to some other really cool animations. There's one of a Glock thats just as good as the STI animation.

Here is another thread on a different forum that nipperwolf linked to on the Non-Glock thread. There are several different types of gun animations. Figured this was worth a mention as well.:cool:

Can anybody tell me why? It's due to "lock-up". The brass case expands against both the barrel and the slide under enough force to cause the barrel-slide assembly to lock-up. The case stays expanded until the bullet leaves the barrel. When the bullet leaves the barrel the pressure starts to fall allowing the case to relax and unlock the barrel-slide assembly. Once unlocked there's still plenty of gas trying to push its way out of both ends of the barrel, enough so that the unlocked case blows out of the chamber and pushes the slide back as it goes.

Hey Tous, are you sure it's the cartridge that exits the barrel? Or is it just the bullet?

;z ;z

Will never forget your (justifiable) chastisement of me for saying "casing" instead of "case"

;f;f;f ;c;c;c

Afternoon, Tous! :)

Scott, you are correct, sir. ^c The only time a cartridge exits a .45 ACP barrel is when you load a 9mm cartridge in the magazine by mistake. ;P

Next, we'll discuss why there is no recoil when using a gun that fires a coherent beam of light. Think phaser. ~ts ~<peep~>

Does the beam arrive at the target in waves, or in particles?
