I think all these so-called 'torture-tests' by youtube warriors are stupid anyway. Who, in the real world, other than actual 'operators' carries their gun in such a way it's going to be full of mud or six feet underwater when they need it? Mine are either secured in my holster or in the safe and if we get submerged by a tsunami or mudslide, whether my guns will fire will be a problem for later solution if I survive.
