boalex207, there's no doubt that purses are not the best way to carry a concealed firearm.
But as a thoughtful student of carry modes, and many other things for many years, I've looked long and hard at the female anatomy for scientific purposes and concluded that most women are built differently from men. They have curves that go inward and curves that go outward and the total effect is dizzying.
They also tend to dress differently from men, except at Soviet tractor factories and similar places where no one seems to care and not even I have been interested in pursuing those scientific researches.
So in this matter, as with much else in life, the proper goal may not be the pursuit of perfection or of the ideal but, rather, of what might be accomplished as best one can. This is hard thinking for gun owners who, by their nature, tend to have linear minds that allow of no compromise in any matter whatsoever. But though they might shun mental curves not even they are likely to produce an inside-the-waistband holster that works with tight jeans or a belt holster that can be concealed in an evening dress.
As for proclamations such as "PLEASE don't let your wife carry in her purse," they perhaps assume a concept of marital relationships in which husbands allow or forbid their wives to do anything at all. How quaint.
You of the double dots, I've seen many good purses that are quite suitable for concealed carry by women who are allowed by their husbands to dress in something other than flour sacks. Coronado Leather and Galco are among the good ones. You might also want to order your wife, or perhaps suggest to her, that she take a course with a good instructor such as Gila Hayes or Louis Awerbuck who understand such things and can help her make the best use of the kinds of concealed carry available to women. There are good training methods for them. Not all instructors seem to know it.
