My guess, either the firing pin is broken or grunge in there has blocked its travel. First, remove the bolt from the weapon and if you can take it apart and clean it. Or, soak in in a good cleaner like CLP and see if that frees it up.

upon closer inspection i found that the "little action release thingy" wasnt coming down like it should. pulled the trigger group and lo and behold there was a ROCK jammed under the "action release thingy bar". this rock looked kinda like the ones in the desert where i last shot the 590. that means it was in the trigger group for at least 125 rounds before it locked up!!

Glad it's straightened out. Another example of why cleaning is a good thing(G)...

Yup, that'll #$%^& it up all right. Since it went over 100 rounds before glitching, we can assume the rock was migrating around the action for that time.While you've got it apart,clean it thoroughly, that rock may have brought a friend(G)...
