The 92 is pretty accurate, fairly reliable if kept clean.
Doing a detailed strip & clean on them, however, isn't for the timid. They're excellent spring-launching devices, launching little springs across the room into other dimensions of time and space...
The trigger on the 92 sucks. Why? Well, look at any exploded view of one. They have to transfer the trigger squeeze back along the right side of the frame to the sear/hammer setup. When you look at the trigger linkage, you can see how it will become sloppy over time with wear.
I'd rate it a 7 for accuracy, a 4 for ergonomics and a 2 for ease of maintenance.
