i just got my c&r and theres a show in  a couple weeks. if i find something i give the vendor the license and i leave with the gun? is there any paperwork that the dealer must generate? tia

The only firearm you can buy from a private party is a C&R rifle or shotgun that is over 50 years old.  All other firearms transactions must be processed through a dealer and you must wait 10 days before you get pick up the firearm.  If you buy from a dealer, even 50 year old rifles and shotguns are subject to the 10 day wait.  You would be exempt from the waiting period if you have a certificate of eligibility from the Cal DOJ along with your C&R FFL.  

thanks so there is a 10 day wait for c&r's. what about when i do a mail order does the dealer at the other end wait 10 days before shipping? im new to this tia.........

The only thing you can legally order from out of state and have sent to you in California is a rifle or shotgun that is over 50 years old.  They are not restricted under California law.  You can purchase any C&R in person while out of state and bring the firearm back with you to California, except for those "evil assault weapons".  Handguns would have to be registered with DOJ within 5 days.
