Default 5904 rear sight change?

Got a 5904 new when they first came out.

Early model with the square trigger guard and fixed blade rear sight.

I want the rear sight gone and replaced with the later models lo-mount Novak style.

Seems to be a well guarded ancient Chinese secret of what the cut is.

Any Novak lo-mount carry or Novak style sight match up to the dovetail?

I can mill the slide top behind the sight if the dove tail cut is the correct angle and proper depth if need be.

TIA

The pre-Novak and Novak cut is the same but you are correct that the rear of the slide will need to be machined. You may find that you need to change the front sight also as the current sight will probably be too short for the Novak rear sight.

The Novak rear sight part number is 107920000.
The set screw part number is 108010000.
The front sight part number is 109090000.

Thank you.

Ordered both sights and the set screw.

Milled the slide .067 down.

Sanded base of rear sight and used my home made sight pusher to install.

Good call on the front sight as the original is to low.
