"Ruger has discovered that a small number of Ruger-57 pistols may have right safety levers that do not meet our specifications and may be prone to cracking. Although only a very small number of pistols appear to be affected, Ruger is committed to safety and is asking owners of Ruger-57 pistols to perform a routine function check of the safety lever to ensure its proper operation and, if necessary, sign up for this retrofit.
