Essentially the idea would be this: Pop-Pops are rebalanced to have a certain smaller limited capacity, merged into a single caliber, given fixed damage attack rolls and also have their pistol skill rolls removed completely. I.E. anyone can make a Pop-Pop attack with the same effectiveness.
It seems weird, why would a pistol not use pistol skills, but there is precedent here with other fixed outcome combat items and I think it would be pretty cool for a few reasons.
+ It would give non-combat characters a themely defensive option that has decent strength for lacking a skill check, balanced by it's limited capacity and disposability.
+ It would let characters with other weapons make use of a quick shot in combat in addition to their other options, which can be useful in niche situations.
+ It would go along with the theme of Pop-Pops being ubiquitous defense tools that are nonetheless not for specialists, something that is not really de facto reality because of how cheap real guns are in comparison.
I think it might bring more fun use to an item that doesn't really have much of a place in the current landscape, and make guns a little more of a presence in the game without at all effecting the mid and upper tiers of weapon balancing.
