Disappointed - Live Free Armory LF22 Elite Series Pistol Slide w/ RMR Optic Cut for Glock 22

Over all I've never been this disappointed with any glock parts I've ever ordered. To start off I ordered this on August 28th it said in-stock. I ordered it with standard 5 day shipping low and behold 5 days later no slide. I called and they said its in back order but on the website it still says avaliable with standard shipping. Fast forward to Oct 20th it finally arrives I go to put it together and the coating on the slide has the firing pin hung up and can't function and now have to go get it polished and clean out so the firing pin will move inside the slide. 10/10 definitely would not buy again. But on a better note it is a very cool looking and nice slide once it works.
