Those Sailor (21c. or even 14c.) nibs are as hard as rock.
I'd consult a trusted nib-tech like Mr. Masuyama who has worked at Sailor, instead of taking the do-it-yourself approach. (No affiliation except a "round-nosed CI" nib grind done in the last decade.)
This is my usual council.
I know that a good many enthusiasts here like to tinker with some or all parts of their pen, but in the case of a narrow grade, 21c. Sailor nib, I'd let the nib experts make the adjustment.
It's more costly & takes longer, but there is usually a guarantee with the work.
