Fox SxS description is excellent. I assumed (maybe shouldn't have!) that the action functioned correctly before the replacement stock was fitted.
I wouldn't be looking for a problem that didn't exist before the 'new' stock came on the scene and the tangs don't always lay in the same position out of the stock as they do once they are tightened up in the wood anyway.
As he says there should always be some slack movement (under trigger spring pressure only) between the trigger blades and the sear bars with the safety off. The safety 'on' should cam the triggers hard down and off the sears.
'bbman3' may have the simple answer too with the hammer being pinched by the new wood a bit.
Lots of little things to check for..
Keep us posted!!
