I ordered the 4th of July special and they received my slide on 20th of July. I have emailed, PM them on Facebook, called, wrote a message on their website...zero response..I sent them my holosun to be mounted also and I'm getting worried. Maybe it's because I sent an FN 509 slide but I see people are getting their Glock slides back and saying they have good customer service...all I want is a response and an update. Does anyone have any suggestions?
