A mate was at the range the other day and was hit by one of the nipples from his revolver.
Turns out it is of an age that they are starting to come loose from the rear of the cylinder...as in, come out at speed when he fires it.
One already hit him in the chest.
Anyone know of firms offering replacement sets?
He says that ideally he'll need the new ones to be a slightly larger pitch or thread to make up for the material lost over time.
Thanks for the replies so far
