To us the 508T X2 is a great duty optic, whereas the 407C X2 is more of an entry level good all around optic.

The MRS reticle on the 508T X2 is nice and gives you options, the larger outer ring makes it a bit easier to find the dot when drawing the pistol. However if you were looking for an optic similar to the 407C X2 but with an MRS reticle, there is also the 507C X2 which is exactly the same as the 407C X2 except it has the MRS reticle.

As for window shape, the 508T X2 has the square window and the 407C X2 has the oval-ish window. The oval window is not as durable if dropped directly on top as the 508T X2 square, the 508T X2 may also give slightly better field of view.
