The lasers can be helpful in learning where you're aiming using the sights. I used my Bushnell Laser Boresighter to check out my Springfield's sights because they were shooting about 4" low at 7 yards. I verified that at 15 feet in my living room using the boresighter. The front sight is too tall. Without a front sight, the pistol would shoot dead on with the top of the slide at the front sitting on top of the rear post, which makes the front sight more than useless, as it's in the way of what I'm aiming at.
It's a great way to practice keeping the gun steady during trigger pull.
