Can someone explain to me what exactly the "Ultimate Trigger Stop" does, and (in your opinion, of course) is it a worthwhile upgrade? Does anyone know if it's a permitted modification to use for IDPA?
Also, it the extra weight of the tungsten guide rod really effective in reducing recoil/muzzle movement? How about that mod for IDPA - is it permitted?
