I've had this model 66 since new in 1978. I like the balance of the 6" K frames. Recently found a period correct elk suede lined Safariland 29 holster for it in like new condition. Makes a nice package.
That there is my favorite holster. I have them in (mostly) black basketweave for K and N frames, in different barrel lengths. I have a few plain ones too, black and tan.
