I also wonder how well these new guns would run if the shooter used a nice gob of grease in the slide recess and on the receiver rails? Especially during the break in period. By design these things require lubrication to operate and Rem Oil (or any really light oil) is about as good as water. When the suspected fault is poor hardfacing, a dry or poorly lubricated gun will have all manner of issues as opposed to a well greased unit.
Agreed. Which is why I normally take along a silicone lubricant when going to the range. I used it on both the Inlands I've had so far. On the surfaces of the receiver, slide, bolt and barrel that move on, over or in one another. On these two it didn't help.
