Superman welcome to the forum......
No way could I ever recommend a 9mm for deer.I don't put much faith in a 9mm period.I put a 41 mag as a min.Like Frizzellr said check your states regulations.I'll be willing to bet it's not legal.In fact I would be shocked if it is.Even though you'd be using a rifle with better velocities it just isn't suited for deer.Buy yourself a short barreled rifle for heavy cover or take a scope off your other rifle and use the open sights.We all owe it to the deer (game) to make the most humane kills possible.I can't see nothing humane using a 9mm in any shape or form.
