Ahh, OK- Sorry, figured it was local.
Don't know what kind of deal you got, but FYI, Northland Shooters has Model 11's for $350, and Model 10's for $495.
So that you're clear, BATFE has no records of the previous/original transfer- so there is nothing to "correct".
When a 4473 background check is done (here, they're done through Fl. Dept. Law Enforcement) there is no specific information regarding the firearm that is submitted. Just your information- and the type of firearm(s) being transferred. All of the info, including the S/N is on the form 4473, but that is retained by the Dealer. No other government agency, State, Local, or Federal- has a copy of it.
And that's the way we want it to stay.
