So, my daughter has fired a pellet gun before today. Allow me to clarify that. She held it, and I pulled the trigger, because she doesn't have the strength in her hand to squeeze the obnoxious trigger on it. However, she has no problem squeezing the triggers on the actual firearms.
That said, check out the video below. It's the last 7 rounds of her first magazine with a real pistol. She's still a little over-eager, squeezes them off more quickly than she needs to fire them, and she tends to flinch. But for a young lass on her first day, she's not doing too shabbily at all!
She's got some learning to do, but she's off to a good start.
And yes, I probably am biased.
