Brownells also has cup tip punches specifically made for S&W through pins.
Ask for Tech Support if you can't find them in the catalog.

To update; I finally got around to putting an XS sight on my Model 60-9.
S&W customer service (should have called Brownells tech support as Onmilo suggested) said that the front sight pin was .050" and that's the size punch I ordered from Brownells. The punch worked fine, but the pin turned out to be .055". It requires a #54 drill bit to install. I'm pretty happy with how it turned out:
