Seeing as I'm new here and all I thought I'd give you a brief explanation on this design. The Backpack I use for everything under the sun is a Dakine 101 http://www.dakine.com series circa 2003 or 2004. These are built mainly for sports enthusiasts so they are pretty rugged, plus they provide a lot of extra clips and clasps so you can pretty much lash the pack to yourself. In the front most zipper pocket there are two hard foam inserts which can hold a variety of things. These are what I implemented for my project.
I recently Purchased an M&P 9mm and it came with a holster among other things. Since I'm left handed the holster really does me little good and I felt it a shame to let it go to waste. The holster was a Blade-Tech Revolution which came with certain M&P's. I noticed the belt clip portion of the holster was attached by three screws. I removed the screws and the holster was easily separated from the belt clip.
Afterwards I took a small pick and made three holes using the holster as a guide. These were for mounting the holster to the backpack.
This is the inside of the backpack with the holster connected to the foam
Here is a closeup of the mounting of the holster to the foam.
Another view of the mounting
With the setup I can fit two mags and the M&P easily into the pouch.
One more view to show it doesn't take up a lot of space.
Basically this pouch does nothing except hold the gun, Not only that if I over stuff the backpack the gun is still not visible. This design doesn't offer the fastest draw times however it will provide me with an effective conceal location.
