^ sounds like the "Smart Carry" holster. I have one and usually use it for an extra mag or two in the summer time, but I've also used it when visiting my Dad, who was shot and seen his friends killed in Vietnam. He says he's glad people like me have guns, but he's 'done his time' and doesn't want to see or think about 'em. Out of respect, when I visit him I lock my 1911 up in a safe in my vehicle, and use my "smart carry" crotch-holster to carry my tomcat, or I'll just pocket-carry it with a pocket holster.
Either way that holster would work well for not having to wear a belt with shorts. The draw isn't as bad as you'd think, and someone really has to touch you in an unusual spot to actually detect your pistol lol I will say, application of baby powder really helps when wearing it!
i also have used it when wearing over-alls, which I like to wear due to all the pockets and over-all comfort (pun intended). but when I do that, I actually use an IWB on the nylon belt of the holster itself, took some getting-used-to, but it's sturdy enough.
