Also known as StG57. Lower DPS than Galil, but has a less awful buff tiles at the stage you will probably use her, because your main tank is probably Sten or something and you'll almost assuredly be running Skorpion that early.

Falls off kinda quickly and has some of the lowest self-DPS among ARs, you won't be using her past the beginning unless you're doing a challenge or really REALLY like her.

The game hates roller delayed rifles apparently.

The new unique equip from the expedition store doesn't help with that, btw. While its stats are excellent (at day…), SIG's base stats are so awful that she's STILL slightly worse than F2000.

Ok, first things first: TURN OFF HER AUTOSKILL AND SET HER TO MANUAL IMMEDIATELY.

Also, NEVER SET HER ON A FRIEND ECHELON EVER.

UPDATE: This is fixed everywhere now so you can ignore that bit.

That out of the way, she's a pretty decent SMG with your choice of permanent passive buff. She renders most of the long-duration-but-average-buff Evade type SMGs completely pointless, having more HP than most, and basically infinite duration buffs you can choose.

Your choice of permanent 65% Evade buff (default), 85% Firepower Buff (2nd choice) or 200% Acc buff (3rd choice). Using her skill cycles between all 3 of them (if you cant tell, they're color coded. Evade is blue, FP is red, hit is orange. If you're colorblind... sucks to be you I guess.) Noone actually uses the Acc buff though. Also if you leave her autoskill on, it constantly cycles between these 3 and it gets annoying. In a friend echelon, you cant turn it off ever so it forever spams it and annoys people.

Oh, and she can load AP ammo, if you for some reason need an SMG that can do that. This does come up sometimes.

Honestly, she's not bad, but there's just...nicer SMGs now.

"Are you THAT short on ARs or need cheap equipment that badly?"

You get much better ARs from story events, and there's only so much that you actually need. If you need a cheap AR and already have FNC though I guess she can be useful.

Her exclusive, while it does give her more strength, doesn't let her outperform many 4* ARs.

At some point, G&K started running out of real guns and broke out more of the early 20th century guns.

Surprisingly, the dolls with them are actually not godawful.

If she's the leader, she gives a general buff, but whatever, most HGs do that. What makes her interesting is that if she's NOT the squad lead, she buffs the hell out of them, thus making her useful in any formation where you want to pack as much as possible into one doll's ability. Lookin' at you, M4, IWS. (And a few others)

MANNERS MAKETH MAN. Very good aura for DPS, and very widely used. As a bonus, she has a very good skill for tanking, and can actually be used as a tank for bamboo spear formations or helping other tanks. She has 40% base crit unlike other handguns (a trait shared with other single-shot pistols like Contender and Thunder .50.) so a suppressor is actually pretty beneficial on her, not that you have other much choice in the matter. But yes, you will be finding use for her. Note that her -acc skill does stack MULTIPLICATIVELY with other acc debuffers.

Her mod keeps her relevant well into higher difficulty content. See info on that here
