"Notching" a Cannon Nose

[GMTrainNut]

I'm working on an NYS&W SD40-2 project, and need to put a notch in the nose as seen here:

I'm thinking about two different ways of doing this. First thought: Glue styrene layers behind the nose, then file the notch into the nose. Second thought: Cut out the area to be notched, and cut styrene bits to fit.

Any thoughts on which way would be best to proceed?

Many thanks in advance.

The first option might be easier, however, it's really up to you.

How about a pc. of styrene square tubing cut to fit by just adding it to the nose.

I agree with Josh. Your first idea sounds like it would work best.

Thanks guys, I think I'll go with backfilling with styrene and filing the notch in.
