Well, I'm not aware of any knock-offs but I suspect that its one of the older models. Why don't you tell us about it It would be nice if you could post a picture of your gun as well and we'll try to help you out with it.
Also, not to be insulting, where are you located? Sometimes Taurus had different models for different parts of the world. For example, recently in the Revolver section someone asked for help trying to find a part of a sight for a Model 90. We had never heard of a M90. When the gentleman called Taurus in Miami they had no idea, until he mentioned that he lives in Canada. Then it started to make some kind of sense.

The picture didn't come with this, but the details have. According to the picture and litany, the 640 is a police pistol known as the PT640 and is a compact similar to the PT140. POLICE is stamped on the barrel. Police pistols are sold to the police only for the most part.
This was, or is not, an imported model into the U.S.A.,so this is outside U.S.A. borders.
I'm nelsito from Manila, a newbie in this site and I also own a Taurus PT640 PRO which I bought second hand from a friend a few weeks back...I've been searching the net as well for materials, reviews, info, pics and even an owner's manual but all I seem to get are articles in Portuguese! :???:
If anyone has further info or links (in English please!) on the 640 & 640 PRO I'd really appreciate it if you can share it with me by sending me a PM or emailing it to me at [email protected]
I specially need a copy of the 640/PRO owner's manual! :'(
Hope to hear from you guys....thanks and safe shooting ahead!
