Glock 43 Failure to Feed and general failures all around

Hey all, I got a Glock 43 new from a reputable gun range in Chicago and I am having some serious issues with it.Check out the video: https://ift.tt/2QkmQVY can see the gun is clean and scoring bullets in this one as well as the initial failure: https://www.dropbox.com/s/3omjerb6df1fzhu/2018-12-06%2022.36.43.mov?dl=0​How would you proceed? I can't carry a failing gun and Glocks are not supposed to fail. That is the whole reason I got one.Edit: additional details. I have about 1500 or so rounds through it. Mostly target rounds but I did shoot 100 of the sig hollow points through it without failure. via /r/CCW https://ift.tt/2RGTiPf
