best photo of spring assembly blow throw ive seen. What you have experienced is a common issue with a specific generation of 4 or 5 models of Taurus semi autos.
The problem occurs hwen the plug holding the spring in, wears down and blows through the front of the slide. the factory fix is a new slide, and a new spring assembly which is a washer placed between slide and the spring assembly.
Since you have the issue, call taurus up and see what happens. So far its beens a return to factory thing.
However you could probably put a washer in yourself at the moment and be ok short term till you can get in contact with taurus.
however if the spring is still IN the slide like the photo, leave it that way.
