For this shape, it better goes "bang" when you pull the trigger. Otherwise, even if it worth $675 or a little bit more on the market, probably better keep $675 IMO ... that's cash and cash does not have any liquidity issue. Of course, it does not bang when trigger is pulled is much better than it bangs without pulling the trigger

Can work safely, is the first consideration.
[Edit] If no plan to shoot it, then, ignore it working condition.
