I have a 9mm Shield 2.0 with the red C-T integrated laser. Nice feature; however, due to the way it is activated (by pressing a button in front of the trigger guard), it may not be available in an emergency, high stress situation. At home, you should have adequate time to grab your pistol and press the "on" button. The housing is integrated and cannot be removed. You can unscrew the actual laser and remove it when the barrel is removed.
