JK,
I just did this last month...Yes the Big Jim's strap on quiver does work on black widow recurves. I had the same question. I really liked the simplicity and compactness of the design. It has a nice clean appearance without and hardware. and it looked like it would be quiet. and took a chance and purchased the big jims quiver. And yes it fits. It's not easy to put on the first time but I have had it on an off several times now and its a pretty good fit. It is quiet, it never moves, it looks sharp. The arrows ride in the right location. I am particular and have to keep my quiver strapped the the thick part of the limb just above the limb bolts so it's extra tight getting it on there the first time. On your PSA i would think the quiver will really hold the arrows tight. My bow is a
PCH with a slightly shorter riser than you bow. Spreading the quiver on your PSA should really do a nice job.
