The last couple of polymer guns I had a stippled all the way around. The only issue I ran into was my shirt getting snagged on the rough texture and exposing my pistol. I would also make it hard to draw the pistol from my jogging holster. So with this new one I tried something new. I first used the wood burning tool to melt down the checkering on the front and back of the grip. Do the undercut on the trigger guard and sand up the surfaces I modified. Then after smoothing all edges where I cut and melted, I did a micro stipple pattern on the front and back of the grip as well as under the trigger guard. I get the good grip and my clothing doesn't snag. It fits perfectly for me.
Nice work on yours.
This is how I stippled mine.
