...fortunately no kaboom.
Remember the principle's of dealing with a misfire... Or a "perceived" misfire.
A good friend and fellow vet was handling the P229 in question when he experienced what he thought was a misfire or "dud" round.
He correctly kept the weapon pointed down range for 60 seconds, then cleared the stoppage and INSPECTED the cause. He rightfully "expected" to extract a live round with perhaps a light primer strike... but instead found and empty shell casing?
Hmm... Didn't feel any recoil? So... Where did that bullet go?
Moral of the story is to understand that even factory ammo can get out with no powder charge in the casing... and that most primers alone produce enough expanding gas to lodge a bullet in the barrel... So... don't just clear the stoppage... Inspect it.
