We have never heard of that size of thread. (.225 x 32 ??) The most common are: 12-28 SAE, 6mm x .75mm Metric, or ¼ x 28 SAE. Not sure what you have. Sounds like an older imported revolver that used an odd thread size. Yes… we highly recommend removing one of the nipples and check the threads first if you aren’t sure what the brand is. Also sending us a picture of it helps. We are happy to assist in this way.
