It is adjustable from 1 1/2 OUNCES up to 3 pounds. I have mine set to 1 pound. There is no creep or travel. I just keep steady pressure on the trigger, concentrate on my breathing and sight picture, and every shot is almost a surprise.
Installation isn't too bad IF you take pictures or study the location of all the springs before removing the factory trigger. The Jewel drops in as an assembly. All you have to do is line up all the components with a pin punch and then push in the retaining pins, forcing the pin punch back out. I have the AI 1.5 chassis system and had to use a Dremel tool to remove a little material from the chassis to get the safety to operate smoothly.
