Wilson Combat gun oil on trigger mechanism, springs, small hard to reach parts, Wilson grease on locking lugs, rails, etc. They make a mix of oil and greases as well thats good for cold weather. Wilson packaging has a little guide on what to use where. Very slick stuff that lasts and stays put
+1 on Berry Hill Ultimate Gun Lube. I use it on the rails of my Glocks and really like it. And a tiny tub will last me several life times.
[Edit] Drats, I see he is no longer selling it, is he even still in business at all?. What a shame. Yeah, I've got mine but it would be nice if it remained available so others could experience and benefit from it.
Go here:I am not sure if this is true, I just recieved a new tub not even two weeks ago. Might want to check again, he may just be out of it temporarily.
