My own experience also, over the decades, is I have seen very few Women who were interested in Firearms or in any of the Shooting Sports.
And, among the few who appear to be, it ends up being one of two things - raised with it and staying with it for-ever and into patches/jackets/competition venues, competition Arms, or, a short term interest began as an adult, which does not continue or evolve even if it may plateau with CCW and once a year half hour practice at a Range and owning one Hand Gun. And, almost nothing in-be-tween.
Back in the 1980s when I was shooting a lot at the local indoor Range, I had many acquaintances, some of whom were Women, and, I ended up providing instruction on request, for a maybe ten or so new-to-Guns Women, all of whom were a joy to work with and walk through the learning phases and details, and, all of whom did very well and took to it wonderfully and were quite good shots very soon on, with good safety habits and attention to detail.
None of my efforts in providing Shooting Instruction for new-to-guns Men, were anywhere near as successful or pleasant or easy!
So, it is ironic to me, and a little disappointing, that there are not more Women interested in Guns and in continuing their learning, acumen, facility, 'collecting', and so on, with them.
