We have determined that some Ruger SR9 pistols manufactured between October 2007 and April 2008 can, under certain conditions, fire if dropped with their manual safeties in the "off" or "fire" position. The pistols will not fire if the manual safety is in the "on" or "safe" position.
We will retrofit all Ruger SR9 pistols starting with serial number prefix “330” (330-xxxxx) with these new parts at no charge to our customers.
In order to ensure correct fitting, these new parts must be installed at our Ruger factory in Prescott, Arizona. We will remove the old parts and install the new group promptly, at no charge, and will return the pistol to you. The old parts will not be returned.
