Interesting... I would have thought that maybe the military variant with the manual safety would be immune to this issue. It seems the manual safety is only a trigger block and not an additional or positive stiker block. It seems this offers no additional safety beyond keeping the trigger guard clear. So much for the military's insistence on a manual safety. Was there really any data showing the units using Glocks had issues related to a lack of manual safety? Sig added one, but clearly it was an afterthought.
