Springfield adj sights

[JulChris]

I have a Springfield full size with adjustable sights (S.A. code: PI 9132L).
I would replace the rear sight but I dunno which cut it is: Bomar, LPA or a proprietary one?
Where can I find drop in sigths with Tritium ?
Thanks

Springfield says that it's a Novak cut.

Yep, Novak.
