A friend of mine recently purchased the CZ Hammered Coach gun and for the both of us the hammers are very challenging to cock. Is there a reduced spring kit or some other gun smithing that should be done so that the hammers come back much easier and still retain 100% reliability?   This is one gorgeous shotgun...like all CZ products   Bugler PS. Neither of us can cock both hammers at once....we all know that is the speediest...
