I only learned front sight by sheer willpower. My left eye is quite useless (20/200) and as a result, when I front sight, I have to let the sight and the target go a bit blurry.

My Glock 19 has the tritium sights, which helps me a great deal - the three dots in a row make it easier to hold focus on the target without loosing the dots.

In the end, the laser was the tool that let me totally change the way I do tactical shooting, because I was able to focus on the target and beyond a lot better. I went from a rail mounted model that was clumsy to the internal Lasermax model, which is well worth the money.
