Ruger recently discovered that all Mark IV™ pistols (including 22/45™ models) manufactured prior to June 1, 2017 have the potential to discharge unintentionally if the safety is not utilized correctly. In particular, if the trigger is pulled while the safety lever is midway between the "safe" and "fire" positions (that is, the safety is not fully engaged or fully disengaged), then the pistol may not fire when the trigger is pulled. However, if the trigger is released and the safety lever is then moved from the mid position to the "fire" position, the pistol may fire at that time.
I got an email from Ruger on safety recall for the MK IV. It said they are taking the guns first come first served and when they were ready to update my Target MK IV they would send me a box and instructions how to send the gun frame only and remove any changes from OEM if I had done any.
They will not send back replaced parts. They said once gun is sent back it will be about a one week turn around time for me to get it back. I also will get a new 10 round magazine for my patience and trouble the recall caused me. It also said the gun should not be shot while waiting for the recall return box.
I believe when Springfield had their recall on the XDS the recall took months to be returned. Granted they didn't have owners wait to send in the guns. They just had owners return them. I guess the way Ruger is doing it they will not have the gun for several months. I wonder how long till I get the return box sent to me? No biggy for me because I have several 22lr pistols to shoot. I haven't had my SR22 out shooting in a long time so I guess it might get the dust blown out of the barrel soon. I bet it has been a year since I shot it.
