Posting this in the orky forums as they'd be the only ones to understand the problem at hand...... Six shooter under-preforms and probably less than 0.01% of the ork population even uses them. Here's a comparison to the other pistols and a suggestion that will give it a niche roll, which is mad DPS. Adding more to the base raw damage would pump it up to be the ultimate DPS, however because of the clip size it lacks an ability the other guns have. That disadvantage being either the ability to down a full healthy enemy combatant in one clip or total damage potential for the ammo carried.
Give it 10x more reserve ammo than current imo. Make it the side arm that has lasting power for long life span play not involving ammo kits and crates.
I'd personally rather it just have a really high rate of fire and reload quick and be a good burst weapon, but a bad general purpose shoot gun, as currently there's already the slab slugga if you want a magnum kinda thing, and the dakka slugga/zip slugga (should really reduce the cost of that to the dakka, as I think it might even have a lower dps) for sustained fire. Just something different then what we have now.
