I, as many other have noted, hated the stock 43x trigger. It made it very unpleasant to shoot more than 50 rounds. I bought the trigger and it installed with ease after watching the video on how to remove a trigger shoe. The reduced pre- travel and smooth face are just what my gun needed. This is an economical option that really improved the gun. It is what, in my opinion, the trigger should have been from the factory. Good product good value.
