It may also be worth looking at the duct runs. Good thought on making sure one has not come loose! Examine them to make sure you haven't somehow developed a leak.
Also, (and i thought this was crap when a mechanical engineer told me this until i tried it and it worked) consider suspending...
I've had 3 taurus pistols - sold 2, kept 'The Judge' because there was nothing else on the market like it.
Fit has been a bit loose on all three, and the finish is subpar.
In general, i've found them to be sloppy pistols, and not quite the same quality as my Rugers, Smiths, or Walthers.
