There is no explaining her like or dislikes.
As far as I can tell, there's "no explaining" the likes or dislikes of
most people when it comes to guns.
But I know what you mean: For rifles, my wife likes deep blue and rich walnut. I like bead blasted stainless and synthetic. For shotguns, my wife likes doubles, especially side by sides with double triggers. I like my old A-5 with the synthetic stock I put on it. For handguns, we both pretty much agree...we both like revolvers (although she likes SAs a little more than I do) but our EDCs are semi-autos.
BTW, my wife had never even touched a gun until about a week after she married me (in 1971). My mother-in-law (who I loved anyway) had a gun phobia such as I've never seen in any other person. And my father-in-law (who I also loved) never pushed the issue...he grew up around guns and hunting, but I guess getting along with his wife was more important to him. Besides, they lived in southern California, so it wasn't like he had a lot of nearby shooting and hunting opportunities anyway.
At any rate, I brought my wife home to Idaho right after we got married. My dad had just bought himself some kind of commemorative Model 94 Winchester 30-30. So he and I, and my brand new bride drove up to "Mud Hill" to try it out.
That was a big mistake on my part. I hadn't realized just how LOUD even a little 30-30 sounded to someone who had never even heard a gunshot except on TV. It scared the heck out of my wife. But the next day I took her out with a single shot 22 rifle and a box of 22 shorts.
As they say..."like a duck to water." By the '80s, my wife had as many guns as I had (still does) and she'd killed as many deer, pheasants, ducks and grouse as I had. And with her Ruger 44 Magnum, she tipped over more steel silhouettes in IHMSA than most of her competitors - including the male ones. She has shot in a couple of cowboy action shoots too, but somehow that never did "tickle her fancy."
Because it worked out great for my wife and me, I've never understood all the advise I've heard and read about not teaching your own wife to shoot. But I won't argue about it either. I figure my wife and I might have had a unique situation in the fact that she wanted to learn about guns and shooting long before she ever met me. The fact is, she still laments over not being allowed to join her high school rifle team because her mom wouldn't stand for it.
