This is such an amazing idea, and so well executed. I carry a Millennium G2 (which is a smaller 9 millimeter) on a daily basis, but even our full sized 9 can be carried in it with no problem and and go completely unnoticed. It comes with a velcro holster that is secured from the inside and holds the gun in exactly the position that is comfortable for you. The pocket it goes in is completely hidden and can open from either side, has locks on both zippers and came with four keys. Im so stoked about this product. It's probably the best purchase I've ever made on Amazon
