I never saw the point in them. you cant work the action one handed, and you cant aim them precisely one handed. I find the Rossi carbine with 16" barrel to be much more useful.
The 16" "trappers" are nice for sure.
The simple solution to your one handed problem is to use 2 hands just like with your stocked 16 inch gun, using both hands while shooting Ranchhands seems to work fine, specially with milder .357, 38sp and .22lr.
The Mare's legs are harder to hold and hit with as the recoil increases beyond .357 but still doable if you have reasonable strength and co-ordination.
A mount and red-dot/laser can also helps with sighting. Once again the point is similar to PGO shotguns..... COMPACT. Are they as easy to shoot as a stocked gun...... No. Is a Trapper full stocked gun compact...... Yes, Is it as compact as a Stocked Ranchhand? No, Is it as compact as a short stocked Ranchhand? No.
A person fishing or bow hunting in Grizzly country might just find a stiffly loaded .357 Ranchhand (or .44mag if they can handle it) more handy then a longer gun.
I do understand why they are not for everyone, just don't quite understand the people who can't see any use.
Have you tried shooting one Stubblejumper? Bit of a learning curve but not too bad.
