Um, there were 4 lines on the 4473's when I worked at Wally World sporting goods. And on call to NICS did all four, if your paying a fee, its your state agency, not NICS. You needed more forms for more guns, but I was *told* that one call could do all the guns, you just had to tell the operator, and fill out enough forms for the guns. We didn't sell pistols, but if you bought 11 rifles 5 shotguns and 1 pistol, the call was for 17 pistols. The forms just have Long gun or Hand gun. Fed gov didn't know what guns you were buying, just those two catagories, instead of asking are you 18 or 21.
