Front Sights for Springfield Armory 1911s
Please Read This-
Factory Springfield front sights are made with the dovetail's ends rounded over. This is done just for style.
My Dawson sights do not share this design. Dawson puts a chamfer on the top corner of each end to "kill" the sharp edge, but leaves a flat edge face to position the punch against.
Dawson's configuration is an improvement over sights with rounded over dovetail ends. With rounded ends, there is no place to engage with a punch to deliver the energy straight into the dovetail joint. With a rounded end, you have to put the punch against the sight blade, which A) offsets the energy driving the dovetail in, B) may bend or break the blade and C) has you delivering hammer energy right againt the side of the tritium lamp (protected by about .030" of the sight body), which can result in a broken or cracked lamp.
