I have gone through my own journey of understanding on gun grease. When I started out, I bought a tube of tetra grease with Teflon for guns. It worked fine for years.
Then I found, by accident, that the moly grease I used for auto repair actually worked better. I gave away the half tube of tetra grease to a friend, who was starting out as well.
Some years later I needed special grease for repairing some food processing appliance. I bought a tube of superlube synthetic grease. It worked as well as the moly , if not better. It is my first choice; it is clear, non-toxic and has very wide temperature range.
There are actually many choices without the "gun" label. They may work even better and are, almost for sure, cheaper.
