JohnK, it's my understanding Ruger doesn't make a stainless Bisley w/adjusable sights (with the rare, collectable, and expensive exceptions noted above). The Bisley Vaquero have conventional fluted cylinders, bright finish, and of course - fixed sights. To get to an SS Bisley with adjustable sights the only practical way I know is thru an aftermarket grip-frame kit. -- Kernel
