Luv it all but wheres the holster?
Finding a holster that fits the taal sights and reflex sight plus maybe a rail mount led/laser, is like searching for hen's teeth! Review by antiflow (Posted on 4/22/2017)

Is it possible to get this Sig P320 RX with the 6 moa Romeo 1 sight instead of the 3 moa?

Referenced product: 320F-9-BSS-RX-10

Unfortunately Sig does not offer this model with the 6MOA Romeo1 preinstalled. We could swap the optic if we have a 6MOA version in stock but there would likely be some small fee because we would have to sell the optic from the pistol as open box.
