I suppose that I might as well chime in here and mention that a lot of Contour runs GStock with KKMs and such. The fact that, for the most part, people don't give us a second look, means that we don't usually get protested.
Not that I promote this, by any means, but many tohers do. It is your choice. My KKM is in the garage along with the B&M. *sigh*
