I have a Gen2 and was having problems recently as well. There are significant differences between mine and yours but the problem with mine ended up being the ejector. I don't believe this would be the case with yours since it's quite new but it couldn't hurt to have it looked at by someone who's intimately familiar with them. I thought it may have been ammo, the magazine I had just purchased, or something I was just doing wrong. Turned out the ejector had significant carbon deposits that was causing stovepipes regularly, regardless of ammo choice.
I'd have it checked out by someone you can trust that knows their glocks inside and out. They might see the problem right away and correct it.
