"Deals" at gun shows in So. Cal are not really what they used to be. You may be able to find some unique pieces from certain of the table vendors, but the prices are most often high retail on new guns, and excessive on used. I found that right pricing may be found outside the buildings at the O.C. shows (Crossroads) when private parties bring a rifle or handgun to sell. Of course, all Federal and state laws apply. Seller and buyer simply seek out a transfer dealer of whom there are a half dozen or so and effect the transfer. The ten calendar day wait applies to ALL firearms unless you've got your C&R 003 FFL for 50 year old or older pieces and a CA COE (Certificate of Eligibility) issued by DOJ. I always bring ALL my paperwork to effect a buy if I find something worthwhile (which for a handgun now includes DL, auto registration for proof of residency, and handgun safety certificate). In fact, sometimes I prepare a checklist before hand depending on what I might encounter that I just can't live without.
