Trigger face too smooth on my M&P?

Has anyone stippled or serrated their trigger face on an M&P? My finger has been sliding around a good bit lately on the smooth surface and I am wondering if stippling it might be the answer. Trying to keep it indexed in the right spot is impossible.

I did a little touch up on my M&P. I didnt want it to be too aggressive, so i used a fine point on my wood burner. I can't post pics from work, but I am sure someone else has done the same. I like the feel.
