Why in the world did TruGlo not design their rear TFO sights to go to the rear of the slide like the stock sights? The long front sight already shorts the sight radius, not extending the rear sights as far back as they can go makes it even worse. My theory is that they must be slightly modifying one of the other sights used on another gun (to save money). Any thoughts? I really like the sights, but the short sight radius turns me off to them.
