Avoid Firearms Lubes Containing PTFE (Teflon) ?

There are a number of popular firearms oils and greases that contain PTFE (Teflon) such as Breakfree CLP , Mill-Com TW-25B grease , Tetra , Birch Casey and a host of others .
Based on research , there are three main issues in order of concern with using firearms lubes which contain PTFE :

PTFE when used in a firearms barrel can experience high enough heat to cause PTFE to form a hydrofluoric acid gas vapor that can cause corrosion and micro cracks in barrels thus shortening their life.
Ditto for breathing in hydrofluoric acid fumes which have serious health concerns .
Using lubes containing PTFE can cause accuracy issues by laying down in unpredictable patchy spots within a barrel once heated .

*PTFE (teflon) begins to breakdown at temps above 450 degrees F and form hydrofluoric acids. A firearms barrel can generate temps as high as 1000 degree F. (especially near the barrel chamber) .... This simple answer would be simply do not use lubes containing PTFE inside of the barrel - only use PTFE based lubes on : slides , connectors , possibly barrel lugs and possibly the last third of the barrel which contacts the slide shroud as they should not reach temps above 450 degrees F in a semi auto hand gun . The outside of a barrel (lug and last third of the barrel) act as a heat sink and should not reach as a high a temp as the inside of the barrel (but I would want to know for sure).

Additional PTFE Notes (from other blogs) :

Lubricating solids (PTFE) in the bore are a variable that cannot be controlled and hence are avoided by serious precision shooters and snipers.
The argument is that the PTFE leaves a inconsistent layer on the bore surface leaving bare steel in spots with a layer of smeared PTFE in spots. Therefore, causing inconsistent pressures and wear within the bore. This is also the case that is claimed to cause accuracy issues.
I can see the points that some make about PTFE. Then there's the concern about the creation of hydrofluoric acid when the PTFE burns at temps above 450 degrees F. which could corrode or cause micro cracks inside of barrels. from the hydrofluoric acid formed when PTFE exceeds it's temp rating (above 450 ~ 500 degrees F.)

*I'm sure there are pros & cons to the above information : Where I stand is why take a chance on using a PTFE based lube on the inside of the barrel (if someone has a heat gauge to measure the outside of a Glock barrel after a couple of magazines shot in succession then that would be helpful) . Most likely , using a PTFE based lube should be ok to use on the barrel lug and last third of the outer barrel surface BUT I would want to know more about actual barrel temps reached first. The slides and connectors should be fine to use a PTFE based lubes . I was a fan of Super Lube with Syncon (PTFE) but now will be using FP-10 , buying Clenzoil oil , or Slip 2000 in oil & grease specifically in / on the barrel because they do not contain PTFE . (of course , there may be other good firearms lubes which do not contain PTFE) .

Your thoughts on one side or the other argument on firearms lubes with PTFE listed as part of the ingredients and would you use them ?
