I ordered on clearance a blackhawk brand shoulder holster for my ruger super blackhawk in 44mag withy the 10 1/2'' barrel.  What a long holster it is.  Its a giant....  Now I gots a single gun shoulder holster for everything.   But i need one more to carry twin redhawks with 7 1/2" barrels next.  I figure to buy a left hand and right hand shoulder holsters and connect them.   Bill
