will take a pic of the trigger and the detent holeTo check whether the body is 05/06 is to take off the eye cover and have a look at what shape the detents hole looks like.
For the frame, have a look at the trigger spur, the bit at the back of the trigger that activates the opti switch. If the spur is off set to the right, then its an 05 frame, if in the middle, then 06.
