Frankly, a .357 magnum, 8-shot, 5-inch barrel, Super Redhawk would be much more useful than a 5-shot, too expensive to shoot, short barreled, 44 special!
For most shooters, this 44 special will be nothing more than a 5-shot, 45 ACP revolver - without the moon clips. Only those few shooters that reload for this caliber and barrel length will benefit from this configuration.
Many more shooters would benefit from the aforementioned .357 magnum Super Redhawk alternative, if only Ruger would build it. If for no other reason, .357 magnum ammunition is much more affordable and available.
