Bad product - Live Free Armory LF19 Combat Series Pistol Slide w/ RMR Optic Cut for Glock 19

The slide was put on my Gen 3 glock frame. Right from the start it was hard to get the slide to go all the way on. After my first shot the slide locked back and would not budge. Had to ask for help at the range from the range operator. He couldn’t figure out what happened. I had to hit it on the shooting platform to get back into battery. I had failures to feed, failures to eject and broke off my new front sight post. I thought this was going to be my edc glock 19 slide but no way can I trust my life with this.
