Suffice to say, a red dot, may or may not be for everyone, but if one does not make the huge effort to overcome an age old iron site addiction, well then, me thinks age for some is the indicator of uses, it took me decades to go to a scope on a rifle, but once i did, well now, ....................along with red dots, so many different schools to learn from, on acquisition and usage, mileage by all will differ,
i have as noted quite a few on carbines, and long guns in general, and a few on pistolas, my canik is a awesome shooter with a red dot, IF i do my part and get it "right"
i wouldn't let any "one" dissenter shy me away from at least making the attempt or go out with someone who has one tuned in and give it a go, change is and can be good, embracing change, makes it so much easier rather than having the "doubting thomas'' syndrome
good luck with choices
