Never have, buzz. My original Perazzi trigger lasted a long, long time. I had borrowed a trigger out of a friend's gun a few times when mine was doubling, but this is the first Perazzi "trigger group " I have ever bought.
Thinking about it, I really have no reason to want to go to a mechanical trigger. Mine has never failed to reset. Not once. The only issue I have ever had was the second sear (top barrel) letting go on recoil from the bottom barrel, and that has nothing to do with whether it is inertia or mechanical.
