On the 44, I strongly discourage a metal sight. Most metal sights are made of softer metal than the (almost always steel) slide in order to compress slightly to form a compression fit in the dovetail. However, the 44 has a plastic dovetail. So, when a metal slide is placed in the plastic dovetail, it is the slide, not the sight, that may be deformed or perhaps even damaged. Using the plastic sights prevents this possibility of damaging your slide.
