The idea is by making them deal with an ammo system, you can increase gun power. This allows guns to be strong, but not be omg, styxshout,wild ride op death mania.

Exactly. The big issue facing a lot of guns is the relatively low power, as they have not been adjusted to compensate for being affected by defense now. After all, don't forget that with a multishot gun, their power is divided across all shots. An ammo/reload mechanic would allow them to be made stronger (which they need) while not just giving them a free "Be OP" card.
