I have them on a few guns. They're very good.
But you already shoot your current type of sights well. If it ain't broke...
What these sights are great at, and presumably why you want them on a duty weapon, is for very fast sight picture acquisition immediately after drawing from holster. They're good sights if you tend to point your gun and look over the top of the front sight, which a lot of folks find themselves doing. They're also great for rapid fire, you never lose the front sight.
