In my opinion, oil doesn't work good enough for slide lubrication. I use Mil-Comm TW-25 grease on all my firearms for slide lube. I use a little dab on each tab, and lube the barrel with a nice light coat of grease. It has worked flawlessly on all my firearms. It is a little pricey but well worth it. I use this on my daily carry HK P2000SK LEM in 9MM, and my USP Expert .45 .
