EXCELLENT!!! Congratulations, and good job to both of you!
IDPA/action pistol shooting is so much more than a fun way to shoot your gun--I firmly believe that the local clubs provide a public service in that we offer shooters an opportunity to handle their guns in a way that most basic marksmanship and range training simply can't. The dynamic situations, and artificial stress of the timer really works wonders on the "administrative" and "practical" side of gun handling.
That there wasn't a day of constant "muzzle" and "finger" calls speaks highly of the training you have provided her thus far. Many many experienced shooters, those who "should know better" who are extremely safe gun handlers at the range just fall apart in practical scenarios.
And for any who are wondering about using a .22, I can't really come up with any reason I wouldn't allow it, especially for a young person, and I think most clubs would feel the same--at least in club matches -- it's about handling the gun, hitting the target, and having fun...not getting caught up in power factors and equipment technicalities.
Be proud, Papa. You've earned it!!
