About the only way to hand-do scallops is to use a round punch with a flat, or slightly concave face.
Hold the punch AGAINST the surface at an angle, and strike the punch.
This will leave a semi-circular imprint on the surface.
Move the punch over so the edges will touch and strike again.
The next row, shift the punch over 1/2 so the rows form a fish scale pattern.
You'll have to keep the edge of the punch sharp.

I did something like that to my G21 not too long ago....what I did was put a medium sized routing ball, I guess it would be called, into a dremmel and after lightly grinding down all the factory "stippling" I just tapped the cutter ball over and over and over and over and over until I was happy, I will try and post pics.

Don't know if you've figured this out yet - but thought I'd chime in with my first post.
Check out leather working tools - there is probably a tool designed to give you exactly the pattern you are looking for. I assume you're wanting to use heat to stipple your texture, instead of hammering away on it. Take the leather working tool and cut the tip off and grind the shank down so it will fit in your soldering iron. You'll need an iron with a single shaft tip, not the kind with the "u" shaped tip.

I don't think leather working tools would be hard enough to cut steel, and the heat treatment would be ruined if the steel were heated red hot enough to soften it.

I assumed he was stippling his grip on a polymer frame - similar to this...

It is a pretty common way to rough up the smooth front grip strap of a pistol (especially the Model 1911 and variations) so as to provide a better grip. Checkering is also used for the same purpose, as is straight across grooving, and even putting on emery paper or part of a grater. All in what a customer wants (and how thick his wallet is).

Stippling or also called texturing is really great when you have a slick surface in the guns front & rear grip surfaces. I have done it to two of my guns, One is a stainless CZ75B and the other is one of my Browning Hi Powers. I have had lots of compliments on both. I actually use half round and round bastard files to do the work. here they are:
