A Shield 9 mm is my everyday carry and has been for a year. I carry with the safety on, and in an IWB holster, have never had the safety move off. So I see no problem in his warning.
The recall is for the trigger isn't it? Not the safety. I have not checked mine yet, will carry the ruger today, and check the Shield latere when I have time.
A bad day at the range is better then a good day on the job!
