I practice a bit of gunsmithing for family and close friends. I have a friend who brought me a pt145 millennium. He misplaced the takedown pin. Other than that it is a fully operational firearm. I have tried contacting taurus to get a replacement part to no avail. I scoured the internet looking for the part and it seems to be a needle in a haystack. I did however come across some pt 140 and pt111 takedown pins and they appear to be the same part. So I was wondering if anyone knew if these parts are the same specs and size and interchangeable. Thank you for your time.
