I am pretty sure your manual describes the proper lubrication of your weapon. Have you read it?
That RIG +P Stainless Steel Lube is one of the few obviously superior developments in the field of lubes, which seems to be populated as much by hype as lubrication.RIG makes a very high performing light grease gun lube. I found that it works wonderfully in all semi-autos for lubing the rails and the barrel contact points. Put a little dab on the tip of a finger and rub a very thin coat over those contact points. Works like a charm. It has made auto 'run' for me that wouldn't work when dry.
The other place it is superb is on the ejector rod leading up to the ejector star in S&W revolvers. They just work better when using RIG lube over using oil type lubes. ........
