I think anyone that states RDS are a great improvement over irons with respect to speed and accuracy at short ranges are overstating their benefits. There are studies that she even the best shooters only benefit a little from RDSs, and poor shooters tend to do somewhat worse.
This is a study that's been bandied about for several years on many handgun shooting websites that suggests the limited benefits of a red dot for most people, while pointing out that lasers have a much bigger bigger benefit than RDSs for most shooters.
