If you registered for the Sept. match that was rained out and did not request a refund, then do not register again. You are already registered for the October match. If you did request a refund, then you will need to register.
Registration opens at 12:01am on Thursday ten days prior to the match and closes at 5:00pm on the Thursday immediately prior to the match. New shooters MUST watch the New Shooter's Briefing video prior to match day in order to shoot the match. For purposes of this requirement, a "new shooter" is someone who has never shot an IDPA match anywhere. Experienced IDPA shooters who haven't shot a match at PSC are not considered "new shooters" for purposes of the required video.
