Selector plate moves freely. I didn't check the cutoff lever directly, but it seems to be actuated appropriately by the selector plate/spring.

I did have one issue when installing the trigger - the trigger spring on the G&P has 2 right angle bends, one on the trigger side and one on the mechbox side. Most trigger springs that I've seen are straight on the mechbox side. Additionally, there didn't appear to be anywhere for the bent end on the mechbox side to be inserted (the plate on the switch body fills up that entire area), so the trigger was very prone to jumping out while reassembling.

I think it's unlikely because the trigger itself is held quite rigidly about its pivot points by the mechbox shell, but do you think the sideways force on the trigger could be affecting its engagement with the switch shuttle? Maybe the force exerted on the switch body by the end of the spring? (the switch body is securely screwed to the mechbox shell though...)
