Most aftermarket adjustables will need a taller front sight. Although if the one on the Taurus isn't higher profile than the Glock adjustable you'll probably be okay with the stock Glock height, which IIRC is .165. On Dawson's site they have .170 fiber optics in .105, .115 and .125 widths. Should be able to find one you like.
I have had good luck with students with PPQ22 and the Glock 44. I think they are both great options.
HOWEVER, when working with a new student, the first thing I do is work on recoil control! Then trigger press and then sight alignment. I tape over the sights.
Hell, I don’t even let them press the trigger themselves (I do it for them) until we have the grip and recoil control sorted out first.
