Quality control issues. - TacFire Glock Slide with Cover Plate

Ordered two of these. One needs a little breakin but I think will run smooth after but the other is way out of spec. Can't hardly get the barrel inside the slide, binds up on the frame when pulled back (with or without the barrel installed). Needs serious help to be a functional slide. I realize these are less expensive lides, but they still need to be in spec or else they are worthless.
