I sold guns for several years. This was in the late '90s and through the millenium so the market has changed drastically.
However, what hasn't changed is the way guns often wind up in women's hands, which is purchased by men who "know what their wife needs" and turn out to be unshootable/usable for a variety of reasons.
The OP mentions the struggle of not being able to run the slide on a semi-auto, which in turn leads to the conclusion that they "need" a revolver, at which point you discover they can't pull the trigger on the revolver. As a salesman, I learned to ignore the husband and focus on just the wife/woman, to include speaking directly to her and making eye contact, and when handing over a gun offering it to her rather than him.
what I generally resorted to was just having them try everything in the case, but there didn't seem to ever be one universal solution, as evidenced by the fact that I can't tell you "the vast majority chose the..." I do seem to recall that some DA semi-autos became managable when first cocking the hammer, then running the slide, but again you wind up with a DA trigger that may be a problem.
IME tha challenge was to find a balance of
- not so heavy that they got fatigued just holding it, but not so light that the recoil was off-putting
- an operating system that they could manipulate, but not at the expense of a trigger they can't pull
- knowing what she wants/needs vs what he thinks she should have
- understanding what the actual goal of buying her a gun might be (real-world self-defense need vs simply starting by getting her to the range and teaching her to shoot and enjoy shooting)
Right now my wife is very into Sporting Clays. She's learned to manipulate the gun without help, provided that it doesn't malfunction (at which point I still have to step in, typically). She's now asking that we store the 870P in the bedroom as she feels comfortable enough with shotguns, but i"m resistant because (a) I don't have a good way to secure it in the bedroom right now and we have kids and (b) an 870 is not an A300. I'm also hoping that *maybe* this interest in sporting clays will lead to an interest in the action games (IDPA, USPSA, action steel, Steel challenge, whatever) so I'm very interested to follow this thread and see what others have had success with. My thinking right now is that if I can get her shooting steel with a PCC or .22 that'll be the "gateway drug". Plan to go stay overnight sometime soon where we can shoot clays in the afternoon and steel in the morning.
