Here are some photos of my rig. I was able to place a nickel in between my safty and the barrel and the safty never rubs the gun barrel. All my components fit snug and nothing is loose. I even looked at my paint job and I can say there are no bubbles in the paint and it doen not come off as I tried to scape the underside of the barrel with my thumbnail. You just got abad egg that's all and I don't blame you for sending it back considering what these go for. I would still send photos or an email to Knight and see if they can explain what happened. I checked my TK and it does have a plastic trigger guard but it is thick and stout and not cheap by any means asI have dropped this gun several times before without breaking it.
