If all it takes is a drop of oil in the firing pin channel or extractor to cause a Glock to go down, they would not be worth owning.
Anyone who does basic maintenance once in a blue moon should never have a problem. I believe a little bit of water working it's way into the firing pin channel or around the extractor is a bigger problem than a drop of oil. A totally oil free part can rust very quickly if exposed to water. Every so often, I remove the firing pin and clean the channel with clp and remove as much of the excess as possible. I then clean the firing pin and give it and the extractor a very light coat of oil. My 11 Glocks run flawlessly.
I hate Chevy Silverado pickups!
