As I usually do when these sighting system articles come out, I have to toss out my two cents and declare fiber optic front sights to be practically (as in practical in all scenarios) useless. If you are attacked outside during the day - especially a sunny day - then yes, they really pop! But at night or even in at an indoor range without bright, direct overhead lighting, they are very hard to see, if not impossible.
The first update I do for all our pistols is pull any white 3-dot or blacked out combat sights and replace them with Tritium, front and rear. And these days, as the article infers, my go to is a red dot. I love the red dot because it allows me to remain target focused instead of front sight focused. And, because I'm a prescription glasses wearing untactical person, a red dot helps even if I don't have my glasses on.
As to point shooting. During the last training class I attended (a 1 on 1 session), the instructor asked me after one course of fire, "Do you remember seeing the dot?"
I looked at him with a smile and said, "Nope." The drill involved a timer and shooting on the move from about 7-10 yards. That timer threw all those pretty sight alignment thoughts right out of my head as I worked to draw, acquire each target, get rounds on target, do mag changes, and get more rounds on target in a multi-target course of fire.
Had I seen the dot? I honestly have no idea. I have worked on draw and present mechanics a lot during dry fire so maybe I did and just didn't consciously realize it. But, I put the rounds where they needed to be, regardless, so I was okay with that.
