If she wasn't left handed, a Glock is what she would have got. I own four, three 40 S&W and one 10 mm, and never had an issue like this. Talking 4000-6000 rounds and not one hick up. But... she is left handed so the controls on the PX4 were of great benefit. Also, the mag release was switched over to left handed. She loves it and once it is running smooth, will be a better gun for her.
