Former WWE star Terri Runnels will NOT go to prison after she brought a loaded gun to the airport ... TMZ Sports has learned prosecutors have dropped the case and she's now off the hook.
We broke the story, Runnels was busted at Tampa International Airport on May 29 when cops say they found a Glock 9mm handgun inside of a sock in the ex-wrestler's backpack.
In pics of the gun obtained by TMZ Sports -- you can see there were AT LEAST 11 bullets accompanying the firearm.
But Runnels told cops the whole thing was a genuine mistake -- saying she had forgotten to take the gun out of her bag after she went to kill an armadillo that was digging up her mom's yard.
