I remember these same arguments when red dots were being considered for rifles. All the older crowd were piping the same old lines:
Fundamentals!
People will get killed when the batteries suddenly die!
You gotta learn iron sights first!
Red dots are worthless and never as good.
Iron sights have worked for hundreds of years!
TWO WORLD WARS!
Ad Nauseum.
The Aimpoint PRO has a battery life that allows it to stay constantly on for over THREE YEARS without needing to replace.
As it ended up, people didn't get killed.
The grumbling old timers were just plain wrong and eventually either retired or had to take their issued rifles with the new RDOs and go qualify.
One such old guy who stopped learning decades earlier kept a state agency stuck in the 1980s for the longest time. He hated any sort of technology. Hated ARs, Hated Glocks. Hated Red dots. Shortly after he retired we sent out a notice and the rest of us who were firearms instructors scheduled a gathering and brought the agency into the new century. Got rid of the Mini 14s and 1980s handguns and replaced them with select fire Colt M4s and Glock .45 autos. Now they have Aimpoints and Surefire flashlights. Welcome to the current century.
Get used to red dots as a modern aiming device.
You can continue to learn and improve yourself or you can stay stuck in the "Back in my day" nonsense.
