Are you having a problem? Or just want to make it run "better"? I have the 410(the 40 cal version) I just make sure that the rotating parts are lubed and slide rails greased and it runs like a swiss watch. For oil I use Mobil 1, for grease I use Mobile 1 lithium grease, had the quart of each for 15 years now, should last through to my grandkids.
