Looks like they may all be like this. They dropped the plunger (great design IMO) for cost I am sure. If you've ever fit a sight into a dove tail properly it can take some hand work with files to get it just right. Installing them the way these new guns are done allows the "assembler" to simply put the sight into the dove tail with no hand work. That's the Ruger way these days. And why not? They come out with a new model gun and people climb over each other to get one. And of course "send it back and Ruger will make it right" is the standard reply. Near the end of 2017 we will hear how Ruger sold even more guns than 2016 They should at least be putting a return call tag in the box with each gun.

They don't build guns anymore....they assemble them!
