The N-frame model 28 is a fantastic gun, but if you're wanting to trade up to a .44, the S&W .44 magnums, (model 29 and 629) are also N-frame, so the reach to the trigger would probably be about the same. If you're serious about getting rid of that fantastic revolver of yours in want of a .44 mag, the only ones with a shorter reach I can think of are the tracker series Taurus revolvers, and maybe the Ruger super-blackhawk.
As far as I can tell, the reach is about the same on my S&W 28, 629, and Ruger super-redhawk. I have smaller than average hands too, I normally wear a size medium glove, but haven't noticed any problems with the reach on these guns, but I normally shoot everything single-action anyways.
