Are maritime spring cups up to the job?  Mattv2099 puts in work:

LOL at the sound of him manually ejecting the rounds.

The vacuum sealed bag is not needed.  A stock Glock will work perfectly well when wet!

If you are planning on being in very wet environments often though it is recommended to swap your regular spring cups (recommended only for use on 9mm Glock models) for special “maritime spring cups”.  This allows water to more freely pass by the firing pin within the firing pin channel.  Having regular spring cups in might hinder the drainage of water and create a hydraulic force within the firing pin channel which in turn would slow the firing pin down enough to cause an FTF (Fail To Fire) because of a light primer strike.
