Security Six Bore Diameter? Make it able to shoot 9mm?

I am wondering if anyone knows what the bore diameter is on a 1980's manufactured Security Six. I am interested in purchasing one and may be interested in having the cylinder milled for 9mm and moon clips. Thank you.

Thank you guys. What do you think about having TK Custom mill the cylinder for moon clips for 9mm? If I was to use for instance a Missouri coated 9mm bullet it is at .356 diameter. Do you think I would have good accuracy? I have heard the Ruger has sharp riffling and even more so in the older guns. I have been thinking about doing this for some time now. I can't think of why not, Ruger makes the convertible Blk Hwk in .357/9mm.
