Ok the prototype is complete (until I find something else to improve upon)
I made it so the pouch is modular and snaps onto the harness. This allows for the user to quickly and easily swap the 9mm/380 pouch out for a .45 pouch without having to purchase a whole new rig for the M10/45.
Harness is still a very lightweight simple design that is similar to a Jackass harness. The holster is made from relatively light leather except for the strap assembly that holds the gun and the leather piece that the pouch snaps onto. These are load bearing components so I made them from very thick leather, but the rest is relatively thin and lightweight, which I find makes it more comfortable, you can’t even feel that you are wearing it other than the weight of the mags and the gun.
I also added a tie down strap on the mag pouch side that attaches to the belt to keep the harness from getting weighed down on the gun side and keep it properly balanced.
I know it’s a little rough around the edges, this was a prototype, I did it all by eye and cut freehand, so it was time consuming. I made templates from this one to use when I make another one, so it will be a bit easier to construct now.
Please keep in mind this is more or less just for enthusiasts and collectors who want a shoulder holster to play around with but don’t want to have to justify it to their wives. I am not suggesting anybody wear this thing on their next big sting operation or foreign dignitary executive protection gig (though I’m sure it would hold up OK if you did) if anything it is a
novelty item.
