Great ccw optic - Vortex Defender-CCW 1x25mm Reflex Red Dot Sight

I did a lot of research and talked to many LE friends to get insight on replacing the cheap plastic optic on my Springfield XD9. I was prepared to drop $800 on a fancy Japanese brand, but Vortex' reputation and this Defender exceeded my requirements. The adjustable brightness is an awesome feature that I wasn't aware of when I purchased. I assume this will help save battery life when I'm not at the range.
