Kimber will send you a screw that is the exact same length as the your current front action screw....
Determine if this is the problem first - Look at SAS's post that I quoted. Can you see similar rub marks on your action? Still not sure? Put some lipstick on the tip of the action screw and tighten it back up - is lipstick on the action?
Cutting a screw back is easy and quick. If this is your problem (the pictures in your initial post indicate that it may be), the improvements will be very noticeable.
