As to the OP's situation, once the gun is back from Ruger you will have no greater chance of malfunction with it than a brand-new untested gun. Anything man-made can fail and you were simply unfortunate enough to get a gun with a defective part.
Good advice, but only if the problem is related to a defective part. If the problem is related to a design
defect (and I'm not saying it is), the chance of another malfunction happening will always
be a possibility ready to rear its ugly head.
