I also decided to taper the tang in the grip area to give the grip a slimmer more graceful profile. My biggest decision was exactly where to profile from. I decided to mount the safety to the bolt and mark the tang at the far edge of the safety shroud. I am trying to avoid an unsightly gap under the shroud when viewed from the side. I marked it with sharpie and then put a piece of tape around the tang so I could grind it.

From that point I decided to taper it to the bottom of the slot for the striker.
