Not sure about adjustables on these models.

What's it for?
You may only need the adjustable sights if it's for target use.

If it's for defense, you can just find ammo that shoots well and thensimply move the sights once to match it. The rear sights are drift adjustable for windage with a brass punch, and the front ones can be replaced with a different height post for elevation to match your defense ammo of choice.

You can always get a gunsmith to put almost anything on them, but I would prefer a factory install myself that doesn't change the gun's normal dimensions.
