So I picked up the Rival Darkside a few months back thinking I'd run it in Limited or Production but I've been getting confused reading the rulebooks. The factory ported barrel and compensator seem to push it toward Open but I know some guys run non-ported versions in Production. Anyone here running a Rival variant in a USPSA match legally? What division are you in and what setup are you using? I'd hate to get to a match and find out my gun's in the wrong class..
