Granted that the Springfield CS is first class but I really don't see much difference between the two except the finish. At the price point of the Para I may have to take a look at one 3 dot sights, 8+1 capacity what's not to like. Haven't shoot a Para and know nothing about their CS but I think I would take the chance and use the extra $$$ for ammo.
Edit: The Para website list 3-dot sights, on Davidsons website it says GI sights. If the Para has the small plain GI sights it would be out for me. I just can't get a good sight picture with the plain GI sights.
