For ccw only - Vortex OPMOD Viper 1x24mm Reflex Red Dot Sight

This product is less than what I expect from vortex. Firstly, you need to remove the unit to replace the bottom mount battery. Terrible design! This would probably be okay for a smaller CCW type pistol. But that's not where I'm putting it. This was to go on a 4 1/4 in Commander 1911 but it's too small a window.
