SIlverfox, the great thing about revolvers is that there are a wide variety of grip shapes you can get. So if you like the gun you can MAKE it fit you by simply choosing the scales you put on the gun.
In double action guns you're pretty much limited to a 10 shot 617. The Single 10 is a single action only gun which loads differently and does not use a DA/SA action. So keep that in mind.
In terms of center fire revolvers watch your options and consider if you'll want to shoot in any matches with them at some point. Both IPSC and IDPA have revolver classes that limit the guns to holding 6 rounds. You can use a 7 or8 shot gun but you're only allowed to load 6 rounds. So for a center fire revolver I'd suggest that you might as well stick with a 6 hole option to allow future competition use if you go that route.
If you want to shoot more in a string simply learn to get fast at using speed loaders. Hell, it's part of the fun to be able to pull off a fast dump and reload and keep going.
I've got both S&W and Ruger double action revolvers. I much prefer the smooth feel of the S&W action. The Rugers have a little "click" in the trigger that happens when the stop bolt is released a little before the hammer trips. The tendency is to use this click as a staging point. But it's not a good habit to get into if you want to learn to shoot accurately in DA mode. Meanwhile the S&W is simply one smooth pull all the way until it simply releases the hammer totally by surprise. It's a small point but one which I notice every time I shoot my Ruger DA revolvers. It doesn't help that those are .44Mag and when I feel the little stop bolt "click" that my mind instantly tries to tell my hands to flinch....
