I do all of my triggers that way. Sometimes I replace the sport trigger with the smooth trigger but I have found if I sand down the ridges on the sport trigger I can get the trigger to where I like it. I also contour the trigger safety.
If you go to the 10:30 mark of this video you can see how I do mine.
