I think the problem might be your jimmy is a derringer and she might be more interested in the Glock 41 Extended Slide like she has grown accustomed to handling.
Well my current EDC Jimmy is a G26. But that is because I am more proficient at handling a subcompact Jimmy. I usually let her handle one of my full sized Jimmys. Like my CZ75 because she does better and prefers a full sized Jimmy to my subcompact EDC. She does think my subcompact Jimmy is cute though. She doesn't like my big bore Jimmy however any Jimmy in 45 or larger she refuses to handle. They shoot to big a load for her.

Joke about naming
A little indian boy comes to the medicine man and asks How do we get our names? The wise old man explained. When we are born the medicine man comes to our teepees and asks the great spirit to show us a sign and the name is the first thing we see when we go outside. Why do you ask, little two dogs humping?
