As the photos show, the rear of the slide does not align with the rear of the frame. I can grip the pistol in my left hand, and by using just the index finger on my right hand I can easily push the slide back so that it aligns with the frame. It requires no effort to do this.
Cosmetic issues is one thing but what I would be concerned with is the ease at which the slide can be moved to the rear to line up.
This could be the makings of a timing issue and I believe Sig dropped the ball by not having the gun sent to them so they could check it out.
