I own a FA83 with 4 3/4" barrel, a Ruger SRH with 7 1/2" barrel, and a Tuarus RB with 6 1/2" barrel. For me, the SRH is the worst to shoot, the Taurus next, and the FA last. I know it doesn't seem logical, but that's the way I see it. I learned long ago to wear a good padded shooting glove with all my big bore handguns.
I mostly shoot 310 gr. to 330 gr cast gas checked bullets at from 1400 to 1600 fps, depending on which gun I'm chronographing. If you feel the lighter bullets will do the job, they will also reduce recoil.
I replaced the Ruger grips with a set of Hogues, and that seemed to help a lot. I also feel that the Pachmayer grips on the FA 83 help a lot, although they are butt ugly. The Taurus is fine as supplied.
One point to consider is that the FA can only be safely carried with 4 rounds, the Taurus 5 rounds, and the Ruger with 6.
