Just a reference of Edith's arsenals while I'm still whacking around with her ref sheet.

The first is Skbk wz. 89 Onyks, the carbine version of Kbk wz. 88 Tantal. Didn't really entered service or production for that matter in real life, but I'd figure if one of my main character have a technically unrealistic gun, then it'd be a nice gateway for any other character to wield more improbable firearms.
Kitted with Mini-Beryl stuff (which is a actually being manufactured by FB Radom but .233 AKs have such a limited magazine options plus it's a heresy.) which have really nice sliding-folding stock, and rails. Plus some accessories: ZenitCo grip and charging handle, a better trigger from ALG Defense, Magpul MOE grip for AK, PBS-4 suppressor, and a Steiner MRS red dot sight. Personally I liked the housing shape, and the fact that it's sits low, since this rail is quite high, higher than the AK-74U rail mount in fact – which is mounted on top of the Iron sight – so that's a plus.

Also I didn't know if it can fit the PBS-4 at all, but whatever.

And for the sidearm is the first gen Springfield XD 9mm. I choose the gun because it had a grip safety, thought Edith would also tamper with the trigger, so it'd make sense. A muzzle brake and Hogue rubber grip to soften the recoil. A pleasant pistol to shoot rapidly.

Edith prioritises convenience with her guns. A reliable, small, light, quiet carbine and a low recoil pistol. Dump heaps of cheap ammo, and you'll do your job.
