Thanks for your comments and insight. I hadn’t really considered how frustrating and inconvenient such safety features could be. I was all caught up in that “dead 20 year old girl” thing. My bad.
Added safety features on guns can be useful but they can lead even experienced firearms enthusiasts into a false sense of security and away from reliance on the "primary" safety. For the inexperienced who don't know the basic rules of safety (who shouldn't be handling guns but do) added mechanical features just introduce added possibilities for confusion and distraction.
