I carried my LCP for 1 week on vacation and oiled it before the trip. The slide is heavily rusted and pitted. My LC9s which I carry infrequently is also rusted after about a month. My CZ75 which I have carried for the last few years is not rusted, even the rivets on my jeans only left brass marks on the finish. Emailed Ruger and let's see what they say. Just trying to let people know how easily they rust so you cab prevent the rust on yours.
