This is not the advice I received from the dealer or my gunsmith. When I got the pistol, it looked like someone had taken a big sqeeze bottle of white handcream and poured it into the insides of the gun. It was way beyond what I have seen in any other new gun I've bought. None of the 9mm and above SIG pistols I have looked at, whether refurb or new, have had this kind of goo in them. Most pistols are shipped with some kind of long term lube in them (Glocks come with that copper coloured paste, for example), but not like this. If I had left it in there, the gun would have fouled up something fierce as soon as I started shooting it. Some of it I left in, particularly in the lower parts of the gun away from the chamber, but most of it I removed and replaced with a little bit of light lubricant.
