For grease
RIG is great , especially for externals and protecting from environment.
RIG+P is great and was designed for the galling of stainless when they first came out, we did not have a problem with blue guns due to blue carbon steel metallurgy.
Eventually the Steel guns metallurgy was figured out ( different alloys for frame slide) and galling is not a problem if metallurgy is correct.
Being a high pressure grease, RIG +P works great on slides, hinge pins on O/U, SxS shotguns and the like.
STOS Dist by Ponsess Warren - is another time proven grease. It really is slicker than owl stuff. Again high pressure areas like the hinge area on shotguns and slides it works real well.
Lubriplate 130 ( I believe that is correct) another time proven
Plastilube as used in the little vial to fit inside Garands , another time proven grease.
Lithium Grease just the plain old time proven grease works as well.
Basically I have stayed with the OLDer stuff. I use RIG , RIG+P and STOS the most, and Lithium because it is cheap and easy to get when I/we get caught out and need something. Singer Sewing machine oil and Lithium has kept a lot of guns running for too many years.
Just like Hoppes gun oil in orange bottle, LSA, and Ballistol has.
Young lady carries a blue bone stock Colt Lt Wt Commander. Hot humid south, and has been raining and supposed to snow. Her gun is lubed with LSA, no grease on rails or internals. RIG on externals and never a problem with rust in the summer or nasty weather, and always runs. She goes/has gone 500+ rds without adding more lube or cleaning.
She goes 300-500 rds b/t cleaning, but she knows that bone stock will run. Loaded with Hydra shocks ( at the moment) - and this gun has fed any hollowpoints from the get -go - I mean bone stock.
