It's a rohm RG 10s revolver. Don't know anything about it other than that it shoots and functions well. It's my friends gun who inherited it and gave it to me for free. I did a bit of research and read nothing, but bad reviews for this thing. All that I have read says its a .22 short but the barrel is marked .22 lr. I cannot remember exactly what we were shooting out of it. We were shooting it last year at his dads so I know that it shoots fine. I don't want it, but couldnt just pass up something for free. I'm looking for two bricks of .22 lr or maybe two Ruger BX-25 mags. I value it at about $50-60 bucks. Maybe someone wants it. Make an offer.
