Post the pics if you can and we'll help narow it down for you. The easiest wat to tell if it is an M1912 is by the rear sight - the 1912's sight is very close to the receiver ring. If there are a few inches between the receiver ring and the rear sight then it's a different model. If you do have a 1912 then there will be stocks on the market in the near future so hang on to it!
