I have Red Dots on my Bullseye guns and really like them. But for a carry gun I just see problems. First they have to be tuned on, is the battery still good, is the sun behind you and putting a glare on the lens washing out the dot. I do not want to depend on a $2 battery to save my familyes life!
Good points.
Like TV's and other electronics RDS have improved tremendously over the past few years. On modern RDS, they remain ON 24/7 yet batteries can last years, dots are self-adjusting to ambient light, even compensate for a tactical light. And a defensive handgun will still have good backup co-witness irons. But knowing which is the best to buy for defensive use is still a matter of opinion, but the cream is slowly rising to the top.
The biggest obstacle for adoption is the cost, but that's dropping fast.
I'm old enough to remember all the jokes when polymer handguns were first introduced. I don't hear any laughing anymore. But I do understand those that still swear by and insist upon a metal frame gun, and good iron sights.
God Bless America and those that have fought for and serve to protect the freedoms and choices we enjoy.
