It will shoot a negligible distance low due to the raised sights required to clear if a suppressor or muzzle device is attached. It won't be as dramatic as one would think Ted.

The Glocks are regulated to shoot slightly high with the factory sights. All I've shot ( working at a range I get to shoot lots of them), even the ones with high sights like this one, have hit a little high which is a preferred sight picture.

think about it this way a bullet does not fire straight and flat it has a curve it starts below the sighting plane then rises above the sighting plane reaches its peek height and the starts to fall. sights are regulated to be on at a certain distance with a specific type ammo but that is close enough for pistol use with other ammo

No both the rear and front sights are "high" (level just like lower sights) and set up to work together for accuracy
