Ive used a Smart Carry daily for a number of year now. Its very similar to the one in the link. I use it as a back up, but I could see using it as a primary if I was in a different job and worked in different circumstances.
A lot depends on what you wear and what size gun you use. Ive used guns as big as a SIG P230 and P239, but I do need to wear pants that I normally dont wear on a daily basis to do so. Wearing "fitted" Carhartt type carpenter jeans, my Seecamp works much better.
Any gun Ive carried while using one was loaded and ready to go. I lead a very active, physical life. I dont sit at a desk or ride around in a car, but run around the countryside all day, climbing in and out of all sorts of equipment and in and out of ditches and structures, etc, and have never had any kind of problem with the gun coming out or going off.
If worn properly, the gun doesnt point at your family jewels, or any other body part for the most part. Maybe your feet or leg on occasion, but thats really no different than any other holster if you really think about it.
Drawing the gun isnt near as bad as you might think, and you can easily do it one handed. It can also be done pretty quick too, and I think its a good bit faster than trying to draw from a pocket. Drawing while seated isnt a big deal either.
The biggest advantage to this type holster is, it can be worn with pretty much anything, and even shirtless with a pair of shorts or with scrubs or sweatpants. No belt is necessary. Its also one of them most comfortable holsters Ive ever used too.
They are waterproof on the back side, and of all the holsters Ive used, my guns that have rode in them have been the cleanest by the end of the week. None of the usual dust bunnies, dust and dirt a normal holster seems to attract.
