I have a gag action bit that I use occasionally and My husband has the same bit that he loves and uses all the time. It was recommended to us by some gaited horse trainer friends who do Cowboy mounted shooting. So I think that's the reason they like this type of bit. Very similar to barrel racing only with attitude
Heres the one we both have. They are Mylers. Any thoughts? Bear in mind these are finished gaited horses used on an indirect neck rein.
