Note in the pix of he Fox guns that the triggers are on the lower tang, aft of the frame. If you have a Fox apart, you'll see that the sears extend out the aft of the frame slightly behind where the triggers pivot. If you bend the lower tang up the triggers move up slightly. They will engage the sears a bit. The triggers must maintain their relationship to the sears. We're talking a little bit here. The sears may not even need to bent at all. At least my Savage era gun didn't need the sears bent. But an early Fox may be different as they start with more drop.
