I just recently sold a .22 pistol to someone on Gunbroker for parts. The gun is intact, but the person just wants the barrel, slide, and innards of the gun. He suggested that I take all the stuff off, but I don't think I'm comfortable in doing it, nor do I have all the right tools. If I took a hacksaw and cut it straight down the middle of the frame, and i kept half of it, i.e. destroying the frame, can it be shipped like this? Is it considered a firearm then?
