Accuracy is anybody's guess. Theoritically a short barrel is stiffer, and possibly more accurate, but I doubt if the great majority of us could tell the difference with a handgun. That's theoretical accuracy, not to be confused with what happens when you put a shooter in the mix.
The slightly shorter sight radius of the 7" barrel might cost you just a bit of real-world accuracy..... but then again, some people's eyes work better with a shorter sight radius.
Velocity drop for two inches of barrel length, probably 50-70fps. Not a big deal (my opinion).
As you can see, I don't have a strong opinion. My 7.5" Blackhawks and Super Blackhawks work well for me. I might consider a .480 SRH, if Ruger would just shorten the barrel to 5" or so, to make it lighter.
