Wingman need a magazine nerf. Having up to 12 shots, while also having among the fastest long reloads in the game (that's faster than most guns tactical reloads) makes a gun that's normally known to be unforgiving for poor aim, suddenly be one of the MOST forgiving.
Either remove the ability to equip extended mags to it completely, or nerf the mag size from 6/8/9/12 to 5/6/7/8. Possibly also nerfing the reload speed slightly. I'm fine with it hitting hard, but right now you can put down so much lead down range with it, so fast, that you can down entire squads without even having to reload.
Peacekeeper... I'm not sure how to fix, exactly. I think nerfing the damage by removing two pellets (so 9 pellets instead of 11, total damage becoming 90 without headshots) and making the spread pattern a 3x3 grid, as well as nerfing the mag cap to 5 would make it feel both less overpowered, and more consistent. I also think shotguns should have a slower draw speed, to make them less effective as a panic gun to rapidly switch to, maybe dropping ADS speed too, to something more similar to the ARs. Give the SMGs and pistols a bit of an extra edge over shotguns, you know? They're big, bulky weapons. Makes no sense they're as fast to whip out as a small, lightweight SMG, while having the same ADS speed too. There's lots of little things that can be done to tweak guns.
Also, Peacekeeper should probably use energy ammo instead of shotgun ammo.
