    I thought that was what was being discussed rather than floating firing pins. When the military talks about "drop safe" they are talking about impacts that can release the hammer.

    My concern is a discharge by any cause if dropped/knocked over/ bumped, etc.

    One more variable to throw on the table (at least for AR's) is the trigger group. Some are less prone to drop induced discharges than others. The Geissele two stage triggers all have a secondary safety sear where the actual sear on single stage trigger would be. In something like an HK416, which has a firing pin safety on the bolt carrier, I think the Geissele two stage setup would bring the rifle to a drop safe level equal to that of a Glock or comparable service pistol. The Glock has a striker safety to prevent forward movement of the striker and a drop safety "shelf" in the frame that a portion of the striker must drop off in order to fire. A Geissele equipped 416 would have the firing pin safety to prevent forward movement of the firing pin and the safety sear in the trigger group, which prevents the hammer from falling in the event the primary sear somehow fails, even when the selector is set to fire.

    It's apples to oranges in HOW they prevent accidental discharge, but they accomplish the same thing through different means. Aside from the trigger safety, I believe the two are pretty close.

    I believe the AUG is drop safe. Has a spring around the firing pin and the way the trigger group is designed- I don't think it would fire if dropped.

    A titanium firing pin in an AR will make it less prone to slam firing. Same for a 1911

    IIRC on the M4/M16 you are supposed to check firing pin protrusion. If the firing pin sticks out too far it can cause slam fires. I could be wrong, I don't have the TM infront of me.
