Thanks, neither have I.
I had a gun I used WD-40 on for 30+ years and never experienced 'gumminess'. It's not a great lubricant, but it does lubricate as long as it's there, as it has a tendency to run off of surfaces pretty quick. But if you use it often, no problem.
BTW I don't use this regimen any more, but it sure didn't hurt my original gun.
Yep, that's what people on the internet will tell you. Interestingly though, no one can replicate this mysterious "gumminess" from WD-40. What WD-40 will do is react with other chemicals in adverse ways. Those that have gunk in their guns after using WD-40 probably didn't clean the other lubricant out before using WD-40.
I will say though, WD-40 is not a great lubricant. Spray some on, shoot a hundred rounds or so and then spray it again to clean it and you'll be fine. However, spray it on and then wait a week, shoot a hundred rounds, wait another week and shoot a hundred more. Then you'll be looking at some issues.
