First, clean it.
Might just be a buildup of crud in the firing pin channel
Next, inspect the pin & spring.
One of those would be the next issue.
While you are at it, clean & inspect the whole thing,
It's a 30+ year old gun, probably needs all springs
replaced, and a really good cleaning.
Heh, looks like we ran the same circles...
for only truly insane people run into burning buildings,
and spent time as a Gov't Ordained Green Monster
