Mines has been fine. Nothing wrong with it, and not too many people, other than a small handful, who have problems or even claim to have that issue. The only issue I had was the phosphorescent dit falling out of the rear site. Which is a common complaint. I replaced them with night sights, and shot Walther an email, and the replacement the phosphorescent sights...

The only issues I had with my Shields were with the recoil springs breaking apart on relatively new pistols...
