Even under those criteria my two Raven 25s are useless. I bought them for $80 for the pair out of impulse. Too weak for hd, too dangerous for carry (they're infamous for firing when dropped) and not really too much fun to fire. They basically exist as a part of my collection but I'm not proud of them. I might've sold them already if I weren't too apathetic to find someone willing to buy the pieces of crap.All firearms are useful, even if never fired, for the simple fact that they add to the Machismo of your collection.
