First, please pardon the messenger. I am fairly certain you have a Chinese copy of a Mauser C96 and I think they were using a Red-9 as a model. The tells are as follows: the dovetail front sight, the crude machining in the milled panels & the grip checkering. I hope you did not pay too much. These Chinese copies are a special market and usually less than half the value of an original.
Regards,
