Pasa001,I welcome you from Omaha,Ne. and today,I pickedup a Taurus PT1911 fore my 1911 collection. And I was wondering about this 1911 since the serial #s start with NAO,do you know of any other problems with this 1911 along with the first 2 batches they madewith serial#s starting with NZ????? Thanks and welcome to the forum. richgp100z,Omaha,Ne.
