I just saw where Trijicon is coming out with a new red dot they are calling Specialized Reflex Optic or SRO for short. I can't find anything on the internet so far but looks like it is going to be made for pistols and much easier to find the dot. Unfortunately they didn't move to a more universal mounting solution but it is top loading battery. I got this information in my news feed from Personal Defense World but I can't find a link to post. I hope this is the game changer some of us have been looking for because the only dot I can find with any consistency is a Vortex Venom on a Smith and Wesson M&P 9 PC CORE gun. Everything else I have tried I look like a bobbing dog in the back window of the car trying to find the dot.
