Total investment in this thing is:
Nylon Mesh Bags (3-pack)..$1 @ Dollar Tree
Tie Wire Roll (free for me)..$3 @ farm/home store
Wrist band (weight lifting)..$5 @ Walmart
$9 + tax for materials to make 2 catchers, the wrist bands are 2 per pack for the $5 price. You can make one for pistol, one for rifle, or make one for yourself and a friend.
I took a good length of the tire wire, maybe 3-4 foot, somewhere in there. Lightly bent one end over so it would pass through the drawstring channel of the mesh bag. I went all the way around the bag to form a hoop. Bent the wire so it was equal halves and marked where the end of the mesh bag drawstring met itself. I clamped my vise at this spot and twisting the wire ends down a good ways until I could fold it back on itself to form of a handle. Once it was sufficient in length, I took the ends and tied them around the top part of the handle. Made the wires in a circular shape to form a hoop. You can remove the drawstring at this point. The double twist of the handle makes it very strong so it supports the hoop well when it's inserted into the wrist band.
From there you can bend the wire to meet your needs so that it will be to the side of the ejection port of the pistol and even rifle. I will test it later on Sunday to see how it performs with my CZ-82. I do have high hopes for it. The bag will have to be behind the muzzle so that the hot gas blast won't hit the bag and melt the nylon, thus forming a hole in it.
