I have a Ruger SRH with a 7.5" barrel, but it is a .480 Ruger. Quite hefty. I have 3 Super Blackhawks of .44 mag, all with 7.5" tubes - much lighter, of course, than the Red Hawk .480. Also have one of those chambered for .45 Colt. The only "large caliber" revolvers I own with shorter barrels are those chambered for .44 Special.
