I think what we need to keep in mind here is that chain-fires do happen, not often but they do happen. Our beloved Italian Repro's are NOT Colts or Remingtons and as such their machining tolerances and final fitment may not be on par with a Rolex watch. The chambers may or may not be all perfectly round, in line with the forcing cone or even straight for that matter. I've got one gun that consistantly gives me "one" flyer for every cylinder, me thinks that there's a chamber on that particular gun that probably snuck past the QC guy while he had a plate of pasta on his lap.
Although what we shoot aren't for the most part originals the design does allow for the errant chain-fire. There is indeed room for the escaping gases and projectile to escape long before critical pressure builds in an out of battery ignition. But as Arcticap stated, 'tis recommended that you keep valuable body parts out of the line of fire and protect your eye balls when sending one of those little round lead balls down range to kill a piece of printer paper, golf ball or what ever evil is at the receiving end of the gun.
