I'm crazy enough to be attracted to mounted shooting . . . got a green four year old mare I started as a long two year old, but she's not ready for shooting off of. It's hard to find stuff on mounted shooting. I got to go 90 miles to meet up with a mounted outfit, and that's been a tough go, weather and all this spring.
I'm sure not in the know, but what I learn from those folks, it's OK to have saddle-bow holsters . . . I notice they are all wearing rigs that are practically shoulder holsters . . .
The "traditional" cowboy hip belt doesn't seem to be too workable when mounted, in all reality. I rode last spring with a friend who likes to "carry", and his rig was basically a shoulder-holster . . . I see that it does make more sense than a belt worn at the waist.
I don't know how many folks are interested in mounted shooting, but you'd think there would be a forum on this site, that's got everything elst
