Are pistols legal for grouse in Colorado?

[Oregon]

Signed in and it would let me buy one for $56 if I proceeded. Funny thing is I was told several times (by random strangers) that my Elk licence included it.
Thanks for the help and I think I'll pass for $56.

I’d pay $56 for a few meals of grouse! Peel all meat off grouse, Sauté in butter, add some chanterelles...pour over your favorite thing you like pouring over. Rice, taters, bread etc.
