I found the answer to my previous question...so...

I now see two different nipple numbers listed for the 6x.75mm nipples for revolvers:

12-50-10 and a 11-50-10. Is length the difference, as it is not listed.

one might be for pistols and the other for rifles The possibles shop list the ones for Pieta pistols with an 11-50 number
 
11-5-xx is the Treso part number. Some sutlers substitute their own catalog number using the format 12-50-xx. There is no difference between the Treso 11-50-10 and the catalog number 12-50-10.
