Gordy,
My husband isn't really into shooting and isn't all that interested in self defense topics. So I do the research for both of us, and keep him apprised of things I think he ought to know.
I absolutely would not encourage him to carry a knife, as he is not willing to take an ongoing class in how to use one. If he had any sort of a problem with hand strength or upper body strength, I wouldn't ask him to rely for his defense upon a tool that requires both.
Pepper spray is useful in some situations, and we've talked about it. My concern for him is that (again) without some knowledgeable instruction in how to use the spray, it's not that great a tool -- especially if one doesn't have a backup plan if the spray doesn't work. People tend to think that one little spritz and the BG will go away. Sometimes it works that way, but when it doesn't, the person using the spray is in a world of hurt if they don't have a Plan B. That's quite apart from any concerns about whether he'd be able to get to the pepper spray in time to do any good; it'd probably be buried with all the other crud under the seat of his van or something when he needed it.
He's getting a carry gun for Christmas, one he chose himself (sort of -- he thought he was helping me evaluate it, but he kept saying things like, "I really like this gun, I think I could carry it ..." and I took the hint). He's already planning to take a shooting class in the spring so that other people can work with him and teach him to shoot.
It is generally a bad idea for people who are married or dating seriously to teach their partners how to shoot. There are just too many pitfalls and too much fallout from the emotional entanglements and the egos of both parties.
Finally, I would note that women are people. We aren't another species! Women generally have smaller hands than men generally do (but not always) and are generally weaker in the upper body (but not always). Other than such physical differences -- differences which occur between men as well -- there really isn't any reason you should be asking men what's best for women. Why get the info second hand when you could ask women themselves?
GySgt,
The sig du jour is for you.
