As for having to worry about the battery, changing the battery in your handgun optic is a matter of being responsible enough to keep track and change it on a regular basis. Just like you need to clean and lube your auto pistol on a regular basis. Or change you carry ammo from time to time. That’s my take on it. IDHolton, I think you will come to love yiur optics.
