I use very little oil on my 930 SPX especially around the gas system. After I remove the barrel and all the parts on the magazine tube I lightly put oil on the magazine tube then lightly wipe off the excess. As I reassemble I wipe off the carbon from the parts with an oil stained rag. After the gun is reassembled I’ll use that same rag to wipe down the entire gun. After my first 500 rounds I removed the bolt and trigger assembly. The trigger assembly was clean, I wiped down the bolt and bolt carrier with that oil stained rag, then before assembling the bolt I put a very small amount of Melitec-1 metal conditioner in the bolt channels. Almost forgot, when I had the trigger assembly out of the gun I ran my bore snake down the magazine tube a couple of times. I run my 930 SPX almost dry, if I were hunting with a field 930 it might be different but because I use my SPX for home defense it’s never outside except when I take it to the range
