Just a swag on that India made pistol, but I "drew in" some lines on the bottom and along the top of the barrel channel of wood that "needs" removed in order to streamline it more.
Removing the top of the barrel channel and tang area is easy enough, and then likely slimming the width as well.
The work comes in when you do the bottom. You would have to look at the RR entry pipe to see if you can thin the web. That's a chore in itself. Then the TG, TP and perhaps the pivot point of the trigger?
I suppose that's doable, but it could get tricky.
