To be fair on the Kel-Tec PF9 thing, a lot of us have gone through the following process:
1) "Wow, that's a tiny and lite little 9mm!"
2) "And cheap too! I can absolutely throw a couple of Franklins and give it a go!"
3) :BANG: "HOLY @$@#@$ @#$@#% @#%$^&^#@@#%^^ THIS THING @^$#^& HURTS!!!! @&%$#$$#%#@#$@#$@^&&!!!!!"
4) "What will you give me for this PF9?"
