It's easy to pick a gun for when you know you are going into a fight, but what dose a runner carry when heading down to a stuffer shack for a meal? What do your runners use for Every Day Carry?
Kind of an area for light pistols in concealed holsters to shine with holdouts being the last resort of the desperate and heavy pistols being harder to conceal. In the core book there are acutely lots of trade offs to consider in the category.
The Hammerli 620S comes with a smartlink and a gas-vent that is otherwise unavailable for pistols, has heavy pistol range and is reasonably priced. It's also carries a tiny amount of ammo, a disavantage that is fast to type but takes a bit to sink it. Man, it's got a tiny magazine.
The Sakura Fubuki is around four times as expensive as the others and has a very awkward reload, but carries lots of ammo, has a unique burst fire option and is one of the few weapons you can carry legally with multiple ammunition types on tap. It's 10x4 magazine system allows you to load the tubes with different ammo. Gel (or Stick and Shock, if you use it in pistols in your game) can be loaded along with a lethal option. Not sure if I like needing to unfold the stock for recoil compensation, might be better to just leave that at home most of the time.
The Colt L36 lacks anything fancy but is so cheap you can buy a few to keep stashed away and add a laser sight or smartlink for next to nothing. It's only drawback is a lack of any features to make it stand out.
And last, the Fichetti Security 600 brings a very generous ammunition capacity, but also has a folding stock. The integral laser sight can be useful for people that don't EDC a smartlink vision device.
Other then a comlink and visual device, what do your runners carry every day? A taser has awful range, but dose have the modest advantage that carrying one though a checkpoint won't require any test on your fake licenses.
