Probably not EVERY Gen5, for instance they're going to make the G17 Gen5 as a non MOS only, so it won't even be an option for the G17. I'm sure the G19 will still offer the non MOS as will the Gen5 .40's and don't forget the G26 Gen5 which for us has never been MOS. I understand what you're saying about paying more for MOS, seems they cost about $80 more but I don't hate it either because one day you might want to run a red dot on it, then you can. If you don't want to, then don't. I have several MOS models but I don't use that feature on any of them at the moment...still more useful than FCS though hahahaaa.
