The two butt hinges are probably more sturdy than a piano hinge anyway. Steel gun cabinets are not safes; a safe is a different beast altogether. The separate ammo lock box inside a steel gun cabinet almost always has a flimsy little lock on it that is easily broken into with a screwdriver. If a thief can break into the main gun compartment then it obvious that the little internal lock box can be accessed. Therefore it's reasonable to expect that ammo should be stored elsewhere or the firearms made inoperable.
I agree totally that the word 'should' is not the same as 'must'. Disappointed that this security update is not more defined.
