Less is more.
Of course, you are right. Those zoomies don’t need gunz anyway, they already have fire extinguishers and fire axes, no need for firearms as well.........
Safety systems don't make the gun safer. They are hurdles, obstacles built into the operation of the weapon to prevent stupid people from hurting themselves or others. If designed well, like on an XD or Glock, you'll disengage the safety in a natural movement without it delaying your operation of this weapon. That's not the case on many designs, and frankly the same reason why these safety systems are so liked (trigger/beaver-tail) is why they are also essentially worthless as a safety, because they impose no real obstacle to use. It's a paradox. The idiot, board and playing with the trigger, will set off a Glock even with its safety.
Stupid people are dangerous, another safety won't help that, nor will another warning sticker. The more crap you put on this tool, the more can break and the more complex its operation becomes. A good weapon such as a Sig, is simple in design and operation. -IMHO
