I will vehemently disagree with this part, and I will suggest that a magazine disconnector safety is king right here. And no, it's not because I see myself grappling with Macho Man Randy Savage and inadvertently losing the magazine and planning to use my single chambered round to save all of humanity.Out of all of the above mentioned safety devices, the grip safety is the most intrusive and the least useful.
For me, it's about being able to practice dry fire with a hammer-equipped pistol and for the striker fired guns, even more so about being able to release the striker for something such as a field strip. To be forced to do either of those things with a magazine installed should only be described as ludicrous, but I suppose I would also suggest the term unacceptable.
