Hello, the heigth of my new front sight is a solid 1/4 inch, my p.o.i. at 25 yards is roughly 2 inches above p.o.a., that works out perfectly for my style of shooting bowling pins, i simply aim at the bottom and hit in the meat of the pin, i deepened the rear notch and widened it a little to correct my windage using a dremmel with a wafer wheel, take it slow ,it does not take much, helps to have a battery powered dremmel and do it at the range, i now have no excuses for a miss, i also polished the trigger and the hammer notches with a polishing wheel and polishing compound i got at harber freight, i just polish i did not remove any material, pghrich
