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

Decent Aura shape with very good benefits. 30% RoF/20% Crit is nothing to sneeze at, and even more from her skill. Used heavily in teams that benefit from RoF/Crit boosts (mostly general use Rifles). Be thankful EN got her with little effort. Also has a 97 dodge, if you need something to temporarily take the front. Also, the source of a lot of Korean memes because she was a total pain to get. Also wears a ferret costume sometimes.

Also somehow still relevant in ((current year))

Catgirl nuns should be met with fire. Honestly has some use but.. you are likely better off with someone else, due to her aura shape forcing you to push her to the side to give your tanks evade and kind of unflattering aura in general compared to other 4*s. Probably better as cores but she does have her uses. For example, combined with Welrod and Makarov, the +evade/-acc combo does funny things to enemy hitrates (though its impossible to reduce hitchance to zero). Niche, but you may find some use for such things.

Or Stechkin for short. Good RoF buff. Actually combos nicely with other RoF buffs if you need more since her aura shape isn't as weird as Calico's. Works well with IWS. Try to grab her unique equip, it helps.

Has a mod that makes her slightly better.

Good early for when you're lacking good HGs. Fodder later.

Also literally retarded.

MURRICA. Usable but not as good as Nagant. Has a smoke bomb (unique among handguns) but the %s arent as high due to 2 star.

Her mod has a completely separate entry.

Generally decent buffs esp. at night, and she can be an evasion glass tank (100 evade!) in a pinch. Not bad if you actually kite your pistols but be wary of her limited HP. Honestly, you want a real tank in front still. With her mod, her usefulness continues due to the fairly good buffs she provides.

Her unique expedition equip is decent (even more evasion), but the real draw for it is when you can use it with her other unique equips for the set bonus.
