Aka P08, the Luger, the... it has a lot of names. Also 1 of the world's most collectible pistols. One of the earliest automatic pistols ever adopted by anyone, and a whole bunch of other honours.

It was however, not exactly a great battlefield weapon (in fairness, pistols in general were not), and the doll is... mostly that. Has FP and Acc tiles. Not as good as the Chinese Mak Clone or SPP1 for those. Unlike those, has a +eva skill instead of a +fp/acc/somethingoffensive skill.

Unfortunately this makes her less consistent than defensive pistols like Nagant, but it has the odd meme use. It is definitely not a practical standard use gun though, and more something you pull out because you for some reason need its weird mix of features (not likely, but it might happen) or are somehow very desperate (much more likely). If you need a night pistol on the cheap though, you're probably better off with... Nagant, Bren Ten, or 1911.

....She has tank stats on a handgun with buff tiles that want her in the back. I'm not entirely sure why anyone thought this was a good idea.

I really want to say something good but the closest thing to a real merit that I can think of is "voiced by Ayako Kawasumi." She's basically a 3 star inferior version of P7 with an... "interesting" shape buff and less used than the cat nun. You are likely to be flooded with cat nuns in your eventual quest for Stetchkin. Also, sends you to jail.

Has a kind of an unfocused buffs that... kinda sorta benefit things? She doesn't greatly benefit any lineups, really, and you can get more usable 2 star handguns honestly. Can maybe replace the cat nun in the meme Welrod/Makarov/P7 lineup, but people don't actually use that formation seriously for the most part. Really better off as cores.

Maybe one day she'll have a cool mod.

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.
