I got my daughter a Shield EZ and we've put around 100 - 150 rounds through it. She is having issues with consistently disengaging the grip safety. I haven't had any issues with it. I'm no pistol instructor, but I'm trying to get her to grip it higher than she sometimes does. Is taping over the grip safety crazy talk? (See video). She has the model with the manual thumb safety as well. Or maybe I should get her some instruction with someone who knows more about these things than I do.
