Will a hang fire actually fire? Is a squib the result of a hang fire? Would you ever re-strike a hang fire?
I think the following comments are correct - and if anyone knows better he or she will offer a correction or expand on the points made...
1. Will a hang fire actually fire? By definition, a hang-fire is a delayed ignition. Some hang fires will fire, after a brief delay -- without your involvement. That's the theory, anyhow. I've never experienced a true delayed ignition is many years of shooting -- and only heard of them. That doesn't mean they don't happen.
The possibility of a late (unexpected) discharge is why there's concern -- the shooter thinking it is a dud round might handle the weapon in an unsafe manner as it fires.
2. Do hang-fires cause squibs? Squibs are typically due to problems in a load that actually that ignites incompletely, driving the bullet into but not OUT of the barrel. It would be hard to tell if one led to the other, and that would suggest both delayed ignition and incomplete ignition. I suppose that could happen... but suspect it's very rare.
3. Re-strike a hang fire? Some folks may do it without knowing it was a hang-fire -- thinking it was a light hammer/striker hit. It may ignite with the second strike -- in which case it WAS a light striker -- or it may not. If you do restrike and it still doesn't fire, you should treat that round as though it is a hang fire -- keeping the barrel pointed in a safe direction.
I suspect many shooters probably consider that failure to fire to be caused by bad or hard primer or light hit -- and clear the round after a second strike (if that's easily done.) That could be a mistake -- and I've done that many times, without really thinking it through. (This discussion might cause me to change my behavior a bit.) That said, true hang fires seem to be very rare, squibs less so, and light strikes or bad primers far more common.
If you're an LEO firing your weapon
on the job in a critical situation and the round doesn't ignite, you'll probably restrike (hammer fired gun) or do a clearance drill (striker-fired gun). You arguably won't want to wait. In that case, If the round is a true "hang-fire" that leads to an explosion after the round is out of the gun -- the cartridge case and not the bullet is going to do most of the traveling, and the risk there is clearly less than the other risk(s) you're facing from the person(s) who may be attacking you.
