I haven't paid that much attention to the Model 69, but swapping the 696 cylinder and hand into 686s, and even 681s, was done a number of times during the height of the 696's popularity, and lack of availability. Is there any reason the same couldn't be done with a Model 69 cylinder? I wouldn't recommend shooting .44 Magnum in it, since it would still have the thin forcing cone of the standard, rebored barrel, rather than the thicker one of the Model 69, but I would think it could be viable for .44 Special now that the spare 696 cylinders have mostly dried up. What do you think? I didn't find any references to this conversion in a search, so thought I would ask. I still have a couple of spare 696 cylinders, hands, and ejectors I picked up for doing a 686 conversion that may or may not materialize, but thought the 69 might be a viable option to cannibalize, too.
