That is wonderful- knowing how to operate a firearm is like knowing how to drive-- if you are ever in a situation where having such a skill might save your life, it's too late to learn it on the fly-- you need to know what to do before the need arises.
All the women in my family can shoot- some are accomplished hunters or skeet shooters, some just like to pop varmints or cans. But none of them will sight a weapon and go "Oh! Eek! An evil gun! Mercy me, what am I to do?"
One of my treasured pictures is my Mom, from about the time I was born-- young, pretty and strong, standing on a dock with a double-barreled shotgun in one hand, and a brace of bloody ducks in the other. That was dinner!
The only gun I ever had a problem with was a 1917 44 revolver. It was flat to big for my hand. It also had a tendency to drop, I kept hitting the same spot in the dirt though.
