What if this was a heavier buckshot weapon, rather than a a boring old scattergun. It would fire a tighter spread of higher damage bullets, represented by visibly larger, and somewhat slower shots, at the cost of clip size, fire rate and reload speed. stats might go a little like this:
+50 percent damage
+tighter spread
+more knockback
+small chance to apply bleed target
-3 shot clip
-50 percent reload speed
-25 fire rate
-very loud shots

tell me what you people who read these things think.
