Depends, depends...depends on the following:
Are you happy with the SA Novak rear?
And are you happy with the POA/POI?
If your answers are yes and no, in that specific order, then send it back to Springfield. Last year I sent back my Operator, already dim, as I wasn’t happy with the six o’clock hold POA it comes with originally, as with the way I shoot/aim I was hitting several inches high at 25 yards. Springfield replaced the entire rear sight changing the POI; free of charge with fresh tritium in under a month.
Yes my front is still dim, but I plan on replacing it later on with an big orange dot style front sooner or later; more to my liking.
So if you want to keep a Novak rear, and save yourself some dough, as well as fixing the POA/POI if it’s not to your liking, shoot it off to Springfield and replace the front with whatever you like.
My 2 cents.
