I’m fairly certain the guys in this video knew exactly what they are doing. However, I am positive that you will not find me dumping dirt into any of my firearms on purpose. Nor will you catch me intentionally dunking ’em in water. I did find it rather interesting that he managed to get his Glock to run once he’d single shot fired it enough to get it warmed up and dried out. The one thing I learned by watching this video is that if you manage to completely soak your handgun in water that it would be wise to get it dried out immediately in order to return it to a usable state of readiness.
