Another option is to dress the face smooth & with hammer re-installed in fired position carefully using a transfer punch mark it through the pin hole & remove & drill it at that point & silver solder in a pin made from drill rod. As mentioned though they don't seem to break as frequently as the seperate pins. Thus while it is a more complicated fix, you aren't as apt to have to.
