Okay, with the spin/slide idea, what is the big difference between the two? Is it simply that spinning is the same contact path without a defined terminal end whereas sliding has two defined ends? Otherwise, we're still talking about two metal surfaces mating, so I'm not sure how the distinction between the two calls for two different compounds. On a revolver, you'd be using two different lubricants in a handful of different places? Not trying to be adversarial, just trying to understand the concept.
For me, I use one or the other and find good & bad in both.
What I like about grease is that it tends to STAY where I put it, no matter how long it is there. (within reason, I'm not talking years here) For my EDC, I like Shooter's Choice grease, the red stuff in the syringe. It lubes up my G29's rails and that grease doesn't go anywhere when carried, and for months if it is asked to do that. Even after a couple hundred rounds, the grease is still there, and it never comes off the pistol and on to my holster or clothes for any reason.
What I don't like about the grease is that it captures grit & filth and (seemingly) runs that filth and grit in my pistol in normal operation. I don't see how running that filth in my pistol can be a wonderful thing... but in reality, I'm talking about a Glock and I can tell you honestly that I simply
do not care about a small detail like that with THIS pistol. A Glock doesn't care about filth and I care even less.
In oil (or shall I say, a liquid lubricant?) I really like FP-10. This stuff is recommended by the (small) manufacturer of one of my favorite handguns, and that particular gun is
very important to me, so I don't mind following their recommendation. (admitting up front that MANY 'recommendations' by manufacturers can be argued as
crap sometimes... but that is another topic of discussion)
FP-10 is runny enough that I do feel as though I need to re-apply to get the protection I want from it, and it will fling around during shooting and likely during storage or carry as well. This is an annoyance, in my opinion, but one I can live with in many cases... but I choose -NOT- to deal with it in a carry gun like my G29.
I'm also a huge fan of revolvers and I'll tell you right now that except in a few isolated cases... I simply do
NOT lubricate the internal guts of my S&W revolvers. I lube the easily visible contact points, and lightly so, again with the FP-10.
I can't stand Rem Oil, and that is for both personal -and- rational reasons, too!
