I think your instinct (common sense) is holding you back. That may be good.
What can one do with a hermaphrodite gun like that? What on earth "could" you do with it? If you are fascinated with the hand-held models like the Judge, and have money to use for fun...then go for it.
But personally- I think all you will have is a $550 whatchamacallit.
I have some better advice.....are you married or have a girlfriend???.....buy her a ring. I'll guarantee you will come out better on that move!
