The primary argument of “you might forget to disengage it in the heat of the moment” is complete bullshit.

Even if you are in that (rather misguided) camp, there are better alternatives. Specifically, a grip safety. Safety automatically disengaged as long as you’re holding the gun properly. Can’t ‘forget’ to do that!

And, yes, there are good, modern designs that use grip safeties. The Springfield XD line, for example. (Those models also require a trigger pull for disassembly, though. Is it that hard to include some kind of decocker?)
