Your comment is rude and not very humorous. In point of fact my comment made no mention of my personal ability. I am 79 years young and have shot in pistol competitions internationally for many, many years. In addition, I have done several armorer's courses in several gun manufacturers and shot along side of many police departments and militaries world-wide My comments were based on my personal experiences over all those years. It is my experience watching so many professional people that carry handguns for a profession that leads me to the conclusion I stated. and it is scary true.
My point is very simple, for folks that carry professionally the only sight system that makes sense is open sights. Those folks need to able to draw, acquire their target and shoot within seconds and hit their target. Most cannot because they simply do not shoot and practice enough. Even if at one point that skill might have been available, without continuous training, it goes away rapidly. Pistol proficiency is very perishable..
Now, if you are shooting for fun, you can accessorize anyway you want, but it will not make you a proficient pistol shooter. If you require MOA accuracy, a pistol is the wrong tool, get a rifle.
