Actually, guns are harder to shoot than that. Standing still, shooting at a paper target, I'm accurate enough to shoot a knee sized target at some distance. But under stress, with the other person moving, while trying to control and stay on a horse...I couldn't do it. Not reliably, even if very close.
State and national laws vary greatly in when someone can carry a gun or shoot in self-defense. It is important to know those laws. I tend to assume anyone trying to pull someone off of a horse in a remote area intends to kill or cause serious bodily harm, which is legal justification here for killing someone in self-defense. But if you ever have to shoot someone, make sure you HAVE to shoot someone. If you cannot accept killing the other person, do not ever pull the trigger.
Carrying a good knife or machete might be a good option. At a guess, tho, the bad guy is likely to act friendly until close enough to lunge...getting a weapon out may take longer than you have. If I had any advance suspicion, I'd simply ask for a trot or canter and apologize for my horse's 'spookiness' as we go by. Beyond that, I think the video has excellent advice.
