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

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.

aka G17 ingame; Used to be decent when you actually needed evasion buffs, but who needs that in current year?

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.

Very good buffs, not good in her own stats though. Skill is blah-ish but serviceable at night. When she gets to MOD3, however. Becomes COMMISSAR NAGANT. May or may not land you in jail (or gulag as the case may be). She does say it herself afterall, about your odd taste...
