Unfortantly it is about 4 inches too high and the rear sight can't go any lower. Should I file the front sight down some?
I am so glad you asked before going ahead... and please don't think I'm trying to make you feel bad for not knowing how these sight changes work.
But for goodness sakes... Please DON'T!!! Filing down the front sight would make the point of impact go HIGHER. You would need a HIGHER front sight to make the impact point go LOWER. Hope you didn't do anything to it yet...
Always remember the following rules...
The rear sight goes in the same direction as where you want the bullet's point of impact (or POI) to go.
Moving the rear sight LEFT, shifts the POI to the LEFT.
Moving rear sight RIGHT, shifts POI to the RIGHT.
Moving rear sight LOWER, shifts POI LOWER.
And moving the rear sight HIGHER, shifts POI HIGHER
For the front sight: You adjust in the opposite direction from where you want the bulet's point of impact to go.
Moving the front sight LEFT, shifts the POI to the RIGHT.
Moving front sight RIGHT, shifts the POI to the LEFT.
Moving front sight LOWER, shifts the POI HIGHER.
And moving the front sight HIGHER, shifts the POI LOWER.
IF you make a drastic change to either front or rear sight and notice that the impact point does NOT shift appropriately and in the proper direction... there could be another problem altogether.
Keep us informed of what you find out.
