Picked up an M&P 22 earlier this week and asked if I should clean prior to first use. The owner said "not necessary", but I went ahead and did a very quick clean and lube. I was surprised at the amount of "grease" in the area of the recall spring guide and elsewhere. I assume this is normal for a new firearm, but there is nothing in the owner's manual about lubing this area. In fact per the manual there are only three lube points. Why would S&W lube in this matter? These handguns aren't being shipped in a wood crate on the storm-swept deck of a ship?
