"Red-dot, non-magnifying, optical sights (particularly the Aimpoint T1) changes the game much more than I ever imagined! With 'normal' shooting positions, their value is seldom truly realized. It is in the roll-over-prone position, shooting support-side shoulder, around cover, in low light, when you're out of breath, that they really shine! Improvised positions, particularly around cover and obstacles, do not lend themselves well to tediously aligning front and rear sights.

for about $20 and mounted it successively onto several of my guns, including pistols.
What I found was that with the tubular units, since you can't see the front sight, sometimes getting the pistol on target takes a bit longer as you wave the gun about trying to find the dot. With practice, however, you learn to get the gun pointed correctly automatically so that when you look through the tube, there the dot is, and when you take the sight off and go back to iron sights, you get on target faster as the pointing is now much more automatic.
