Pinned and Recessed are

Model 66: no-dash and -1s.................

Model 19 no-dash through -4s..............

might be easier to find a 6" 19 than 66.



SS/66s are easier to maintain when carrying in the woods.........

If it's not your primary hunting gun ....... I'd go with a 4 or 2 1/2" for ease of carry.........................
