For something like that, I go to Ebay and search for "vintage K frame holster" or some other combination of words. 4 or 6" holsters are plentiful, but unfortunately sellers are getting wiser on value of some of the better brands. I know I picked up some pretty good ones for less than $50 over the last few years. My own favorites in used are Don Hume, Bucheimer, Safariland (but only the leather, not the polymer) and Bianchi. I must have a couple hundred by now, something for every gun in the safe.
