The long heavy trigger pull is the same safety that revolvers have used for over 100 years. That and a good holster is all you need to make a machine that is handles under the 4 rules a safe machine. The number one safety is YOU. The fact that the gun needs 8lbs of energy added to it before it can fire makes a safe gun. It is not a case where the ability to fire is there, and some mechanical process it keeping it from working, the equation to fire are not all there, you have to add that last little bit (8 lbs).
