I don't own an MX10 but know two guys who do. I do own an MX8 Sporting and they are very similar guns.
The MX10 comes with either a removable selectable trigger with leaf springs or coil springs. The leaf springs generally have a better trigger pull while the coil springs are more durable. Mine has leaf springs and they aren't difficult to change. I had to change one after 50 thousand rounds, the second after 80thousand.
The only other issue I had with mine was needing to replace the top lever spring at the 80 thousand mark.
IMO, Perazzi is a great gun. I don't think you'll go wrong with an MX10 combo. If I were getting back into trap it would be the gun I'd choose.
