What type of rear sight cut does the SA GI.45 have?

[AirmanAtwood]

I'm trying to change the low profile rear sight with an adjustable. I have no clue what cut it is though. Is it LPA or Bomar?

The GI and the Mil-spec use standard dovetail low and high-profile rear sights respectively. The Loaded uses a low mount Novak rear sight cut.
