Unless you are an armorer or trust yourself to do so, field strip and clean as per the manual. One extra step is very well worth the effort....if you can do it yourself or have someone do it, you might take the firing pin out and clean the tunnel it rides in. I have seen some neglect in that area that leads to the gun malfunctioning and even bent firing pins. On the safety, when I take out the assembly, I clean it then polish it and the slide where it it mounted with a rag and metal polish (no motorized tools on a curved surface). I then use a tiny bit of grease on it when I replace it. Makes a world of difference in how the gun operates and saves blisters on the thumb.
