I'm planning a camping trip where there is a near by lake we will be fishing canoing and boating and probably scuba diving. So I'm getting wet. I use to live in Florida I lived near a beach so we where always fishing and boating. I have a Glock 30 that usually goes with me on these outings. It has several times been submerged in salt watter, never intentionally but its happened. I usually just shook the watter out of it and soon as I could i submerged it in fresh watter for a few minuits to get all the salt out of it. I would field strip it and dry it best I could with what I had and wipe a light cote of gun oil sometimes motor oil (but that was temp). When I got home or if I went straight home I would disassemble the gun completely I wont do this with my other handguns I just know how Glocks work I'm too chicken to take apart a 1911. Clean and oil it up and go on with life. Now I will be carrying my Glock with me. I have a holster I picked up back in Florida at a dive shop that was made by a local toon. The holster is made of kydex and nylon and some other materials. He markets them to scuba divers and boaters. If you knew you where bringing your gun into the watter would you do any kind of pre care for the gun? Are their any special lubricants or stuff to use on it. I'm not planning on discharging it under water! The reason its going with me in the watter is so I know where it is. I don't want it out of my sight. Ive got a big knife if the poopie hits the fan under water?
