All I can say is take her to a gun shop and try one on.
In the fall of 2007 I went to our local pawn shop/gunshop to buy some 20ga shot shells, Tagging along were my two daughters age's 6 & 11, they wander'd round the store while I made my slection, I could hear excited preadolcent girl voices I peeked round the corner to see what was up, they were fondleing a hot new youth size Jimney Cricket manual single bolt action in .22Lr with a stainless steel barrel and a Pink synthetic stock, I ended up buying them the Cricket and a box of 20ga ctgs. Today thats been the single best impulse buy Ive ever made (cricket).
I figure any firearm that excites preadolesent girls is fine by me, they are good shots with it to, mabe because of the rear peep sight?, the manual cocking knob is a nice touch from a safety standpoint.
Yes it has a Pink synthetic stock, yes it has a black plastic cocking knob, and a plastic front sight as well, but all cheesiness aside that hasent been a detractant, they havent broken anything off it yet and they still grab it every time we head out hunting chooseing it over other .22 single shots like the Ithica 49, Savage73Y, Marlin 110, and the Stevens #30, the coldest we have hunted with the crickets was -26F, hunting the state bird, the size and proportion of these little rifles is just right.
The girls liked the pinkie so much Lil Brother wanted one (non pink .22) so I bought another in Blue steel and Black synthetic.
once they master ther marksmanship they will graduate to the taurus 72c/ss, a very cute looking stubby stainless .22mag pump carbine.
once they are better hunters they can graduate to Dad's semi auto's, like the two Remington's one a 522 viper and a 552 speedmaster, and a stock ruger 10/22.
As I recall Rossi, H$R (not a typo), and Henry, Marlin, Savage,Mossberg all market single shots.
Cricket does sell other replacement stocks includeing adult size in synthetic and wood for the more traditional look.
