Seriously, I believe a quality bra manufacture could come up with something far more comfortable and durable. This would bring a whole new meaning to Victoria’s or (Victor’s) Secret.
You're exactly right!
I spent several months designing my own under-the-shirt shoulder holster for a j-frame scandium .357 snubby (11oz empty, 14oz loaded), because I didn't like anything available commercially (and still don't). It was a LOT harder to get right than I expected. I had thought it would be easy for such a small and light gun.
To get REALLY good concealability, I had to reverse-cant the gun very slightly (which makes for an even slower draw than with vertical positioning), and also position the grip quite close to my armpit. Good concealment also requires that the gun be snugged in close to your body, and with no freedom to flop around at all.
After I was finally satisfied with my design, I realized that the whole difficult problem of designing a harness that can conform to the compound curves of the body had already been solved...by brassiere designers! If any of us guys were confident enough in our masculinity, the quickest way to get a good harness would be to buy a brassiere, and just cut the cups out of it. But I doubt that any of us could handle that.
Women have a big advantage on us there, but I suspect most women wouldn't tolerate the fact that you need to use a somewhat loose-fitting and opaque-printed-fabric cover shirt to get good concealability out of this scheme.
And I agree with you about the need for an undershirt...I wouldn't want to wear my harness on bare skin. But that's not a problem for me...I don't use my shoulder holster in the hot summer, when I don't wear an undershirt. In the cooler months (most of the time in Colorado), I normally wear it over an undershirt, and then cover it with a roomy flannel shirt. Conceals better than anything I've ever seen...but it's definitely NOT a quickdraw.
