Lobo, that is one good looking piece. Are you doing much shooting with it or are you mostly a collector & who made your mount ? For the other guys who "educated me" on the Rail Mounts, i did not know about S&W predrilling the 686s. Thank you for your info. My 4 inch 686-1 does not have the holes, however my 2 1/2 inch snubbie 686-6 does.
