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

Aka M1887. She's a shotgun, so she will do shotgun things shotgun-y (read: facetank with her armour), but is not particularly impressive at it. Her stats are okay (but worse than most other 5* shotguns), her tile buffs are the weakest of all 5* shotties (and most 4*!)… and her skill is downright useless, because it has a ridiculously long 15 second cooldown and if you can use it appropriately, well shotguns aren't what you want to use for that fight.

As far as free SGs are concerned, a minor upgrade over 97S if you don't consider 97s's mod.

She can reduce enemy eva at night, which helps for some specific weird shit, but it isn't likely to come up.

Suffers from not only being an MG, but an inconsistent one due to her passive. Her stats are alright, but her passive skill is unreliable, not that it matters much since it only activates on reload. The active suffers from the problem of activating slowly enough that you'd expect MGs to have already killed most of what you'd want to stun anyway.

She actually has a decent hybrid skill and statset except she's locked behind LSC and a shit campaign grind so you'll probably have better by the time you can get her.
