So, 20 armed swat team members or combat troops in full gear moving around, switching off safeties and such aren't going to make noise, but the tiniest noise of a flashlight switch is going to give their position away and ruin the day? If the bad guy is close enough to hear the switch (and not the 20 guys in full combat gear behind it), he's close enough to be a goner as soon as he turns around.
I say it doesn't matter if a forward clickie actually clicks, as the momentary mode is always silent. I would futher say that twist momentaries are not tactical, because if you want constant on light, twisting the switch could take far more time than it should (and can require two hands), and there is the chance of the tailcap being locked out and you getting no light at all.
Of course it does, the OP bashes them every chance he gets, and doesn't even own one.
