Ruger has discovered that some Ruger American® Pistols chambered in 9mm may exhibit premature wear of the locking surfaces between the slide and barrel which, if ignored, can result in a crack developing near the ejection port of the slide. This typically does not occur at round counts below 10,000 rounds. The condition is easily identified during routine maintenance and cleaning, and the crack should be visible long before the pistol becomes unsafe to shoot. Ruger is committed to safety and is asking owners of Ruger American® Pistols chambered in 9mm to inspect their pistols for excessive wear or cracks and, if necessary, sign up for this retrofit.
