Pattern it and compare to the type of shooting you plan to do. It the patterns are too tight for your shooting then consider opening the chokes or installing choke tubes.
If you invest $300 - $400 into having choke tubes installed in this $900 gun please realize that you will have $1200+ invested into a gun that will sell for a little over $900. So... think about what you really need. Spreader loads might be a better option for the occasional grouse hunt. Or, having a professional open one or both chokes might the solution. Buying another shotgun with open bores/cut barrels for $500 is an option.
But if you really, really want to spend the money on having choke tubes installed, it's your money and your gun.
