If you buy a hand gun over the Internet does the 30 days start from the time you buy it or from when you take possession of it from the ffl you are using?

take posession

I agree. The clock starts when you put the purchase date on the P2P form, the actual day you take possesion of the handgun.

the 30 days actually starts the day after you take possession of it, either from a dealer or private seller

the 30 days actually starts the day after you take possession of it, either from a dealer or private seller

Take special note of "the day after"
