Does not come with all required hardware - HiViz LiteWave H3 Tritium/Litepipe Pistol Night Sight Set - Fits Smith & Wesson M&P 380 Shield EZ

Expert states in question above that it comes with all required hardware which they should be ashamed of themselves it in fact does not come with a new screw for rear sight and more importantly it does not come with the commonly lost at the range clip that retains the front sight. Which due to their expert answer is the reason I purchased this set. Now I still cannot shoot my gun because I have to wait another week for a retaining clip that it did not come with waiting for shipping from another vendor, someone with real experts.
