I’ve been using WD 40 for about 20 years. I first learned of it (and the benefits of spray carb cleaner) when on an Army Combat Pistol Team.

I was the OIC of an Army Pistol Team. If my CSM ever saw me using WD-40 he'd tar and feather me. I have used Brake Cleaner (same thing as carb cleaner) to great advantage once I learned it will just disintergrate anything in the way of plastic mags. The army would never sanction WD-40 in any official sense. Most of the stuff we learn comes in the form of sage advice from the old hands, right? Sometimes sage advice is more urban legend.

I use Amsoil MP (Metal Protector)

It sprays or wipes on, then dries to a lubricating film that doesn't attract dust.

I wouldn't spray it on my ammo as there's a chance it MIGHT screw up the primers.

It dries fairly quickly on the gun, so won't seep into the ammo if you wait a few minutes to load.

You can feel the action in a revolver is smoother after using it.

None of what I have is plastic. Even the grips are wood.
