You probably don't want to hear this, but, if you're willing to travel a bit there are a few rimfire USPSA type matches a month. For example, Central California Pistol League (CCPL) has a "fun" match on the 4th Saturday of the month. Oakdale has a fun match on the first Sunday of the month. I think Laguna Seca has Steel Challenge once a month. If you want to do centerfire pistols, Richmond has matches on the 1st and 3rd Sundays of the month. CCPL has a match on the 2nd Sunday. Oakdale has a match on the 3rd Sunday. Northern California Pistol League has matches twice a month. There's a lot to shoot, but you have to be willing to travel
