Grease or oil

[chief38]

You usually can't go wrong following the manufacturers instruction booklet that came with the gun. If used and no instructions came with a gun, they are easily found online.

Once in a while I will use something other than what the manufacturer recommends but that would only be for a specific reason on a specific day. For the most part I use oil. I grease mainly old rifles that call for grease.

I thought grease was preferred on slides until I found out it doesn't work real well in cold weather. I was using Tetra on a 1911 slide in freezing temps and it froze up the slide. I went to oil and never had that problem again. Probably why the US military uses CLP instead of grease.

They have a better solution for new weapons but it's applied in the manufacturing process and not available to the unwashed masses.

CLP works for me. Of course if you don't shoot in freezing weather it doesn't matter.

Many people just use Mobile 1, which is a synthetic oil. If it works on the internal components in a combustible engine it should work on a pistol slide.

All I use is Mobil 1 10w30 for gun oil
