Once I have the throat of the grip pretty close I mark out the shelf/sight window.

I use the I-Beam as my centerline reference and just grind her down on the 6x48.

Flipped around doing the shelf side


Rock it back & forth a bit & this is what I'm left with after the 6x48.

Here they are after taking them to the narrower Rigid & getting even closer to a finished shelf.
Tonight I'll finish out the shelf & get rid of all the 24 grit marks
