When the slide is locked back, there will be looseness in some parts. If there were not movement in the guide rod, the pistol would not function.
You could get someone to "tighten it up", but then you could have reliability problems.
If the firearm is safe to shoot with commercial ammo, and the safeties working as designed, and no one has mucked up anything with home gunsmithing, then let the buyer decide.
