Taurus Model

Pictures may be helpful. Taurus made lots of 9mm pistols. Most would have a model name or number engraved on the slide.
Polymer framed pistols, striker fired pistols. Hammer fired pistols. All metal pistols, etc.

A few pictures are worth a thousand words when it comes to telling you what you have ... Taurus has made many , many different 9mm's over the years .
