I have been looking for some time and they are just hard to find. Gunbroker and Guns International have about zip. I missed out on one about a month ago, seeing it late afternoon only to return in the morning to find it sold. I found this one today as I headed to Best Buy in the city to pick up my dash cam, no second guessing this time. A 3" RB M65-5 that, though clearly fired, appears about new. And, yes, as many have said it is about perfect in the hand.
