TechDoc, are you sure there's a safety on the spine? I wonder if the safety is essentially incorporated into the lock mechanism. In that scenario the button lock has to be depressed while pushing the thumb studs (at least until the coil spring assist engages). That would address the only issue I've seen with the Barrages sometimes springing when dropped on the floor (yes - I fumbled mine a couple times and had that happen). Not that that has ever been a big issue, but companies have to always look at liability. We live in a lawyers world.
