Congrats, I was fortunate to find a Weirauch version, the HW-80K (Carbine) in .20 caliber, my advice is to find a pellet it likes ASAP and buy a bunch of them, I have two .20 caliber air rifles among a dozen or so ,17 and .22 cal. air rifles and IMHO the .20 is my favorite all around caliber air rifle, but they are getting scarce, and so is the ammo, I have about 8,000 pellets stocked up and I'm shooting (no pun intended) for 10,000 as a goal.
Be sure to let us know how she shoots, mine likes H&N FTT the best.
