Glock does not call anything back, usually they wait for you to call them. Even if it's a problem they are aware of.
Several years ago when Glock messed up the frame rails, even after several PDs notified them, even after the problem hit the net, they didn't recall anything. Left plenty of suspect/defective guns out there in holsters to be used and on shelves to be sold. If you wanted one of the replacement frames they had ready to go, you had to call them.
The local sheriff had 4 of 200 new Glocks break the first few rounds put through them. Glock said, yeah, we know about that, it's rare (4 of 200?), don't worry about it. They said keep using them, let us know if anymore break, we will replace those 4. The sheriff told his guys and gals to stop using all the new guns, and told Glock they would replace all of the new guns. Glock did, after the local story leaked to the press/net. Everybody else still had to know to call Glock if they wanted replacements.
Worked well enough before, should work well enough again.
