I am a strong believer in the AMS Oil synthetic greases, (been using the stuff for over 20 years on many different guns) they maintain their viscosity in every environment I have been in with mine...
from MI -20 to AZ 115+ left the HK sitting in my car (AZ) and the gun was so hot I could not touch it but still the greese kept it's consistancy!!!
Just a light coating on all the load bearing surfaces... n they are great on keeping the mags rust free....
