1) Sure, just need to find a customer willing to meet the MOQ.
2) Yes, all standard 92s made after 1984 with slide mounted combined Safety/Decocking mechanisms. G models are incompatible due to the plunger angle on the right side being different.**
You CAN put the modern levers into a G, but the right side plunger/spring traditionally used in the G can't be used, nor can the F style plunger/spring used in the conversion kit be used, so it may not function 100%.
