Do you plan to reload?
If so, will you shoot only hot loads or will you do reduced loads?
I went with the 460 8 3/8 standard S&W model. I didn't like the look of the PC model. The 460 seemed more versatile as far as brass and bullet choices. I bought mine only for target shooting. The longer barrel (8 3/8 in my case) is front heavy, but it is welcome when shooting the hot loads. A shorter barrel would balance nicer, but it would have been harder to find. I love shooting light loads with trail boss powder. I think the longer barrel will help with recoil, but 10.5" is really long. The 14" version has a bipod with it.
I have only had my x frame out twice, but the second time around I was getting quite comfortable with it. I absolutely love the gun. I was shooting some mild loads single handed at close ranges and doing well. I shoot steel competitions and plink at the same targets afterwards. I think I will get better with the barrel weight as I practice.
Good luck.
