Just one more 1862 Police nipple question

[KLNC]

I would like to install Treso nipples on a Uberti 1862 Police.  I've searched for the answer, but am still confused.  There are the Tresos for modern Italians, including Ubertis (11-50-16) and then a size for .31 Caliber Modern Italians (11-50-30), which are slightly shorter.  I know either would probably work, but since the .36 caliber Police is built on the .31 small frame, would the shorter 11-50-30s be the best choice?

I'm new to this, so am hopeful the wiser heads will pitch in and help me.
