I am looking to buy the Trijicon HD night sights for my new MC Operator but I don't know which one to get. They have one for the 1911 novak cut, but they also have one that says for springfield. I have heard that springfield has a different cut than a normal cut so would I go for the springfield version? Or is that only for the springfield xd's? I feel stupid for asking but need to know. Thanks.
