So I started looking for basic iron, black sights for a Glock 34 Gen 5 MOS (optics later) and I'm looking at the Ameriglo GT-5504 model

Ameriglo makes a GT-504 for generations 1-4 and a GT-5504 for generation 5.

What changed between the generations? The rear sight slide cut? Front sight mounting method?

I'm really having problems finding the GT-5504 model, but the GT-504s can be found and I'm wondering if there's a way to substitute.
