Extended safety
Product installation was straightforward. The operation movement is smoother than factory. The extension makes for a faster release and access to the trigger. The only downside and why I gave it 4 stars is there is no red to show on the safety when in the fire mode position. None is shown on the product description photographs so this is not false information. While this isn't a problem for the experienced person I feel having the red paint show is advantageous in the event another person, not as familiar with the weapon function, handles the weapon. Overall I'm happy with the product.
