I'd like to replace the all black Novaks on my SA 1911-A1 9mm with night sights. Novak obviously makes a set and Wilson also makes a set which will retro into existing Novak cuts. My question is I doubt either of these sets is available for 9mm. That is, they will be preadjusted for a .45s POA/POI. Will the 9mm print that much differently or am I just creating worry were there is none?
