cupped pins

[hobby-gunsmith]

I have a S&W Russian new model navy #3 double action and need help in choosing the right size cup-tipped punch that would remove those pins. Brownells sells them but I would rather not buy the entire set. I believe the right size is .072" (1.8mm) long or .066" (1.7mm) long. Speaking with David Chicoine on antique firearms assembly/disassembly book, he thinks the right size is the largest but he can not be sure. Any help is appreciated.

Not knowing, I would get the smaller one. It is the most likely to work
of the 2 choices.
