I can tell you that my TTI M2 trigger is outstanding. I've never felt another shotgun trigger like it. He must have added material to it because it seems to have a lot more "magic" than a stock M2 trigger!
Also, I have a triangle Versa, and honestly I never could get quite as fast with it as I was with my old FNH SLP. If anybody is looking to get into a Triangle Versa, I might know someone who has one...
