4seventy, you are absolutely right, most have only trigger blocks, some have blocks that block the sear from being disingaged, then on the hammer rifles you have the stalking safeties that is a slide the actually engages a slot in the hammer that blocks it's movement, so the rifle can be carried with the hammers cocked. The Barred safety is a system that blocks the safety button from being pushed to fire possition. As you know there are many types that work in different ways, but all supposidely insure the tumblers stay away from the pins till you are ready to shoot! The intercepters, you mention, were an attempt to guard against doubleing caused by heavy recoil. The intercepter is moved out of the way of the tumbler only when the trigger is pulled for that barrel. The problem with these is, if the rifle does attempt to double,and drop the other tumbler, the second barrel is left uncocked without the shooter knowing it till he pulls the trigger on the second barrel. SUPRISE!

If the intercepter was not there, and the rifle doubled, at least the target would likely recieve the second shot as well!

All I was saying was,without going into the pages it would take to explain all the different types of safety systems, that the hammerless is cocked all the time,if it is loaded, but because you can't see the tumblers, you pay no attention to the fact it is cocked, and depend on the safety, which is not always SAFE! Yet people worry about a hammer rifle, which is far safer to carry loaded, as long as it has rebounding hammers!
