Need help with nipple size

[user 52142]

Howdy everyone. I picked up what I believe is an,
International Arms
Italian made
Corsair
Double barrel Percussion pistol
.44 cal

Would like to upgrade the nipples. Not much info online about these pistols.
Online search says everything from..
6 - .75
6 - 1.00
1/4 - 28

Hoping someone here might have a Corsair and could verify which size.

Thanks in advance
Bill

Take your nipple to Ace Hardware. They have a device in the section that sells screws etc that you can test it on.

Thanks Bighorserider. I'll try that this weekend if no one can confirm before then.
