Springfield Range Officer Front Sight Dovetail?

[Candyman87]

Good evening all-

Will be installing new sights in my Springfield RO and am looking for the dimensions of the dovetail. I've measured the dovetail at .340" which I understand is typical for a Springfield. However, I'm not sure if its a 60 degree or 65 degree cut?

Would like to order the correct dovetail file to maintain the angle rather than going with the 60 degree file and trying to maintain the angle.

Thanks in advance!
