Anyone here ever tried one of these t-shirts that have a holster sewn into the side?

It looks like a neat deep conceal system, although it might not be the handiest one should you need your gun in a hurry.

I would think with out some type of harness the weight of the gun would pull it down making it uncomfortable.

I had some body armor in a tee shirt type carrier I ended up sewing shoulder straps into it to surport the weight.
