They should swap the striker clip with the AA-12, striker is fine with less bullets and the AA-12 could use more..or just give them the same clip size .

Take a look at the shotgun balance threat v3. We need reinforcement!

I completely agree that this gun needs more ammo.  I regularly get 5-6 hitmarkers on upper body shots before I get a kill, lightly tapping trigger to slow fire.  That's maybe 4-5 kills based on given ammo.  I would like to see ammo increased and either a range or damage buff.  This shotgun is completely in need of a rebalance.
