    I have heard of triggers that have been sent to people like Allor, or Wilkinson, to be "tuned". What do they really do to a trigger, like a perazzi trigger, thats usually pretty good from the factory ? Educate me,......please!!!! Thanks,.........Rob G.

    How do you

    They spend the time adjusting it that the factory can't or won't spend on it. They modify some of the parts (make new one's if necessary) and carefully assemble the trigger to set the "pull weight where the shooter wants it and to remove all creep and slop in the linkages so that trigger breaks cleaning exactly when the shooter expects it to.

    Tuning triggers is not an activity for the ham-fisted or the uninformed. It requires skill and knowledge to know what to fiddle with and what to leave alone.

    There are a number of things to do to tune a trigger:

    1. Test fire the trigger to find out what needs to be done.
    2. Check the weight of pull with a scale.
    3. Take the trigger apart and clean.
    4. Square up and polish all the bearing surfaces.
    5. Replace the trigger spring inorder to get the correct weight of pull.
    6. Square up the hammer notch and sear mating surfaces and polish.
    7. Adjust the amount of sear engagement to eliminate any creep.
    8. Test fire the trigger to see if you did a good job. HMB

    HMB has it exactly right. But the person to do that is Doug Braker. Easily the best "filer" I know. Others can be found, Crenwelge is another (Phillips gunsmithing). Either of these guys will fix youright up.
