It depends on what you want to adjust. There are many different ways to adjust a Tikka T3 trigger, and it really depends on what you need or want to change.
If you’re looking to adjust the weight of the trigger, that can usually be done by adjusting the screws on the trigger itself. If you’re looking for a lighter or heavier pull, simply tighten or loosen the screws until you reach your desired weight.
However, if you’re looking to adjust the travel of the trigger (the distance it needs to move before it fires), that’s a bit more complicated and will likely require some tools and expertise. In most cases, it’s best to consult with a professional gunsmith to get this kind of adjustment done.
