In my never ending quest to educate anti crossbowers who insist its a gun, I've been doing a little research on the "trigger" mechanism and comparing it to a traditional bow release. The principle operation of both devises seem similar, but my question is...guns have firing pins, or a hammer, that connect with the ammo which in turn ignites the gunpowder causing the gun to shoot. In the case of the trigger on a crossbow, there is no hammer or firing pin, only nocks that are indented to release the string when pulling the trigger to rotate the nock to a new position. As in hand releases with traditional bows, they have a lever to activate the release operation. They don't call it a trigger, but again, isn't it the same principle? Am I out in left field with this line of thinking, or have I stumbled on something that may have some merit as far as declassifying crossbows as guns?
