I'm positive. Unless she was talking about a special State form I'm not sure what she was talking about. As far as form 4473 goes, I just ordered a new stack which arrived last week. On form 4473 there is a place for the make, model, serial number, etc. but there is no place to write in or a checkbox or anything concerning pistol grips, regular capacity magazines, "assault weapons" etc. Next time you buy a gun feel free to turn the yellow form over and look at exactly what information is contained.
The NICS check contains much less information than form 4473. I can run the entire NICS check with just your driver's license and the knowledge of whether you are buying a handgun, long gun, or both.
Here are the required items for a NICS check:
Last name
First name
Sex
date of birth
Race
State of Residence
Country of Residence
Checkbox: __Handgun __Long gun __Both
There are boxes on the online NICS check for social security number, height, weight, and middle name, but they are all optional and not required. I never input them in order to save time.
There are NOT boxes for the make, model, serial number, or caliber of gun. The only identifying feature of the gun on the NICS check is Type, and all long guns are just long guns, even the "evil" ones with pistol grips and 30 rounds mags.
Again, please understand that I am talking only about the federal level. It is entirely possible that your state has some extra laws that require FFLs to keep records of pistol grips and other "assault" features, but there is no place in the bound book, on form 4473, or on the NICS check to state that a gun has any scary features, and there is no place on the NICS check to state anything about the gun other than handgun or long gun.
