There were some made. Less than 100 though IIRC.
The majority were used on 50 pre lock, unfluted cylinder, 6-shot, 3" barrel "L-comp" like 586 revolvers. They were 586-6's, again IIRC.
Your best bet is to contact gunsmith "Vito" at the Performance Center. If theres one left floating around, he would know. Good luck! Regards 18DAI
