I witnessed a catastrophic failure of a sig p 220 Equinox today. The barrel separated from the chamber to within an inch of the muzzle. I've never seen anything worse even on the net. Couldn't believe the guy didn't get hurt.
Do you know what type of ammo he was using? It looks like it generated a lot of pressure with no where to go meaning the barrel was plugged with a round still. Either way he sure was lucky. Now my next question is has he contacted SIG to see what if anything they will do about it?
That almost has to be from a squib. Or a bad ammo load. Is that a 45? Was he using shooting Federals? I seem to remember a recall not long ago by Federal of a batch of 45 ammo that was loaded with the wrong powder, and they were causing guns to do just that.
