I have an XDM in 9mm and I've typically oiled it pretty thouroughly. I put oil on a q-tip and go over the slide rails and any part that looks "shiny". I also put a couple drops on the spring and wipe an oiled patch around the outside of the barrel everywhere. Then I was told this may be too much oil since it will seep out particularly along the slides. It was suggested that I barely need any oil and to cut way back on the amount I put on. So, I guess what I'm asking is how much lube does it really need? Thanks!
