In my opinion, guns can get wet. My duty gun has spent days in the rain where I've had to dump water out of it. There was nothing about this holster that could harm the finish, so I just used the actual gun. Usually, I use a blue gun, but I didn't have this model. After a quick cleaning, dry and oil, the gun is just fine. Also, my holsters are so tight during wet molding, that a plastic bag rips right off and becomes a PITA.
