I am now in my mid 70s and my eyesight is such that i can either focus on my sights or my target, which means my accuracy has taken a hard hit. This weekend i went thru a number of combat shooting drills and did several with a Sig P227RX which has avred dot sight. What a world of difference. I now want a compact with a red dot! The range master was a Sig guy and recommended the P320 and P229 in compact, but i am wondering if anyone is carrying a ccw with avred dot and what you might recommend.
