Fit isnt right - Cross Armory Performance Flared Magwells For Glock Gen 5

I tried to install this on my gen 5 glock 34. It took a whole lot more force than I think should be required. And the screw that comes with it won't reach with the large grip installed. Also, once it was installed, it would hold the mags. Now it made it easier to load, but you have to pull the empty mag out. I would guess it wasn't milled properly. I tried to reach out to Cross about it, and they only asked if I was using a lanyard. Haven't heard anything in over a week now. Wondering if anyone else has had these issues.
