So much depends on the school of gun. This gun has a soft radius in front of the toe, but fairs out gently away from the lock panel along the bottom of the lock and sideplate, and sweeps softly away from the panels toward the tail. Any crisp delineation is done with low relief carving, as in the beavertails. I doubt anywhere the relief height is more than 1/32", as the finishing will make all of this 'pop'.
Some builders use a rat-tail file all the way around the lock panel, but again, it's school-specific.
A slight radius at the nose only, and then a gentle planing away from the mid panel to the guard area.
Then the relief line is cut between panel and guard.
Top edge of sideplate panel is a tapered slope, not a dished out hollow. While this may be right for this gun, it may not be for yours. Simply food for thought.
Then this photo is posted just to knock your sox off.
Not a lot of 'meat' around the lock. Not an even reveal, or flat, all the way around either. I like to look at a gun build as a soft, living thing; no straight lines, no hard geometry, it's all about the flow of form. What would it look like if it grew up as a creature of the air or water? Again, this is school specific advice, and this particular gun has much European influence, far more than American.
