Glock grip reduction/reshaping

[feudist]

Is this allowed now in Production or Carry Optics?
I'm referring to the reshaping to a 1911 grip angle that can be done.

I have recently admitted that I don't read the rules so take it for what it is worth: the stuff that I've seen done on the guns whose owners shoot major matches makes me believe that anything goes these days.
