I HAVE seen or experienced it before because it's DIRECTLY based on existing designs. I can't claim that Ice Breaker or the Vex Mythoclast are mechanically inaccurate because there is no real-world counterpart for these things. Changing the ammo used in a weapon doesn't change the mechanics of it when the mechanics are obviously directly based on an existing design. The weapon is meant to function the same as a modern revolver, so it should be comparable to a modern reolver, regardless of what it shoots.
