Made this for a client! It is a simple envelope style padded nylon chest holster in Camo Green 483 500D Cordura with Ranger Green webbing and USMC Coyote Brown buckles; holds the .45 plus 1 magazine.

With gun and magazine out
Angled view showing generous drainage for both magazine and main holster.
The 1″ webbing is elastic, so the retention is positive, and the 1.5″ webbing is standard Nylon, wide for comfort and more than long enough for me at 3XL with ability to go up 2 shirt sizes approximately. The primary retention strap is able to accept a vertical strap looped to it for belt retention if desired; or for suspenders to go through. It can be also used to hold laynard to handgun if desired.
