Do you think

That when you have a pistol, hit a man on the back with the butt of the gun, but you hit the man so hard right on the spine, that all the bullets inside the magazine of the pistol starts firing inside the magazine...

Do you think this is possible?

you need some sort of spark to get the bullets to start firing, so i don't think so.. most firearms are design to withstand serious punishment

yeah man the bullets.. they just came out on there own.. i just wanted to use the gun as a club for hitting my wife in the back of the head for fun..

Dorado, you'd need some serious power to crush those casings while inside the clip. The pistol itself would be smashed to do so, and by the time you get that pressure, the pistol is going through the person instead.

So the answer is no.

If the gun rattles enough so that the firing caps of the bullets hit something to set it off, then maybe.

But guns are made so you can hit someone, or something, and not have any damage to the gun or bullets
