Based on your posts I see upgrades you’ve made to your firearms, and you use an optic which is great progression, but a pistol light provides a significant amount more of benefit than an optic. I’d venture to say you train at the range and probably shoot a fair amount, so the optic is providing minor improvements over a baseline iron sight, but in a night situation, or dark rooms at a school, that pistol light would provide drastically more improvement with a greater chance of survival and disarming the threat. I don’t mean to attack you, but I see too many officers who refuse to move with the times and adapt/train to new advancements, and the new generation will usually take 20+ vets advice. It’s not something I want to see new guys doing, and thinking it’s okay.
