I've been using the Castrol marine grease for about 5 years.
So far, so good. I put an ultra thin layer on the slides / contact points. Then I use oil as I have in the past. They seem to work better than they did prior to the grease.

Ah, gotcha. Yeah Super Lube is a commonly available brand of grease with PTFE.
You never told me you had free samples.
Is that the white stuff?
I'm really glad we've got a lube expert on the forum
Is there a ppm or % of PTFE in a grease that you would consider necessary for it to be effective and not just marketing wank? Also, do you know of any greases that have both PTFE and ZDDP?

Effective in what application?
I assume a gun slide or trigger ?? If yes, then very little would required, but on a slewing ring on a Siemens Wind Turbine, it could be as much as 25% of the thickener or soap.
Some greases are designed to be general purpose automotive, general purpose industrial.. you get the idea.
A gun slide or trigger sear is such a small contact surface relative to a heavy industrial application.
ZDDP or zinc has been around almost as long as Teflon. It is used as an anti wear additive mostly and especially in hydraulic fluids.
It was discovered a couple of decades ago to be toxic to aquatic life and not rapidly biodegradable, so a lot of manufactures have moved away from is and replaced it with modern AW additives.
I haven't seen too many greases in my world that advertise ZDDP as a selling point, but then again, I don't see everything! I work in industrial and heavy commercial settings where the large lube manufacturers have products best suited for specific applications.
Remember, regardless of what the thickener is, or what the additive package is, it is still the base oil, that is suspended in the thickener that does the majority of the lubrication and corrosion protection.
The niche product companies just don't have much presence.

Currently I’m using weapon shield grease. No issues so far.
This is just my opinion; I'm not necessarily trying to change anyone's mind. If it works for you, fantastic.
I had someone recommend Weapon Shield to me during my search for the source of my mystery Berryhill gel.
I ended up looking at the SDS for weapon shield and refusing the recommendation after reading it.
I'm not the expert in lubrication like VMAX, but my expertise in my field kicked in.
Weapon Shield is just diaper rash cream with a very small amount of some proprietary stuff called "Steel Shield" that is advertised for just about any application you could imagine.
No idea what Steel Shield is

Thanks for the info. At least my guns won’t get diaper rash! That’s important.
I’ll consider other options. Much appreciated.

Ah, yeah I guess that's pretty important. I'm probably looking for a unicorn, but I'd like an all purpose grease that is good for engine assembly or gun parts. PTFE is "magic" and ZDDP is a good and inexpensive antiwear additive so it would be cool to have both. Silicone free since it's going in an engine.

Ah yeah, redline is good stuff and they put a shit load of zinc in their oils. Probably the same oil they use in their grease but who knows...
I found it!

This used to say "Berryhill's ultimate gun grease" or something like that.
You can still see a little of the metallic blue color that used to be on the label.
The grease is still in good shape. No apparent oxidation or cracking that I can see. I don't even know if grease can crack.

Anyway- it's as I remembered:
A very thin, red grease that has the consistency of good cherry pie filling.
It has a metallic sheen while in the can, and it seems to shimmer in direct light.
It may be placebo, but I feel like it is noticeably better than the Lucas "gun oil" I'd had on there while I was looking for it.
As a nice confounding factor, I got the slide and barrel as clean and dry as possible and applied Militec 1 to the rails after heating them with a pen torch.

The slide on my CZ is like a teflon covered loogie now.

That looks like Slide Glide.
