I have a mid 90's Model C (no last round hold open, fixed sights, shiny slide). I was going to send it in to be fixed for a few issues but I'm afraid I will get a newer model back so I decided to fix it myself. I received new parts today such as re-coil spring, firing pin and springs sear spring and sear cam. My question is this, what parts should I oil, what parts should I grease and what kind of grease? Any other input is also welcome. This is the pistol in question.
