    Got bored today,so i decided to drop a Wilson three hole trigger into my new Citadel.It seemed to fit fine.I dry fired it a couple times.Then, I did a safety check.The thumb safety worked fine.Then I tried the grip safety.The hammer dropped without touching the grip safety.I checked to make sure everything was installed correctly,which it was.Switched back to the factory trigger, grip safety functioned perfectly.
    Any ideas ?

    you need to file the front of the grip safety arm so it swings down to block the trigger bow.
    The Wilson trigger bow might be a little longer than the factory trigger bow.

    if the Wilson trigger had the tabs by the trigger shoe, you might be able to ad a little more pre-travel and that might get the grip safety to work.

    Well, I am still tinkering with this trigger.I finally got out the ol' digital micrometer and took some measurements.I found that the rear of the trigger bow on the Wilson is a few thousandths of an inch shorter(top to bottom) than the factory trigger bow.The grip safety barely engages the factory trigger bow.So, that fraction of an inch difference in size is enough to cause the grip safety to not engage with the Wilson trigger bow.So....I am going to order a Wilson grip safety and some other parts I want to upgrade.
    Thoughts/advice?

    you could peen the GS arm and lengthen it a little to engage the trigger bow.

    Need a welder or simply replace the GS.

    I would prefer that is possible. If not peening is the only solution.

    The hammer shouldn't touch the grip safety in the first place when activated. The GS's only job is to block trigger movement when disengaged. Other than peening or welding, there's 2 other things you can try !
    Put the trigger pad in a vice, and gently bend the trigger bow slightly upwards, depending on how much free play you have in the frames trigger track. Another trick is to file a little material away from the outside of the lower split tail area of the GS, which will give it a little more outswing.
