Things I liked:Fits well and a cost effective alternative to other products made for target rifles and pistols. Things I would have changed:Add a center groove across the middle of the shoe to aid in positioning the fingertip. (I really need to buy a mill) What others should know:I installed this with the trigger shoe inverted with a slight angle to the right (right handed), as I like how the pad of my finger rested in the same location. I removed some molding flash to smooth out the contact surfaces. This shoe makes the 46M more consistent to shoot, but it takes a while to find the sweet spot where actuating the trigger doesn't move the sights left (trigger too far forward) or right (trigger too far rearward).
