Not sure what s weird about the fixed modified choke but I have the twin to your gun and use it for everything from doves to quail , preserve pheasant and yes even grouse in the thickets of the Appalachians try it as is you might be surprised. Mine is pretty effective on all the above. I really don't worry much about choke anymore. As I said shoot it some before spending your $$ you might be pleasantly surprised.
