looks good to me. probably different runs of barrels from the factory. some had a witness hole and some didnt.. if it locks up into battery fine and shoots with no case head seperations or bulging id say you're fine. it looks ok in the picture. your loaded chamber indicator is normal as well.. if it was a 40 s&w id be a little more cautious maybe, but i think you're good to go to the range.. just my opinion call ruger lol...
