The gun in the picture is a Beretta Tomcat. With all three clips loaded, and one in the barrel, the whole rig only weighs 1 pound and 13 ounces. That is 31 rounds of 32 Auto. I can't imagine ever needing that much ammo, but the two spare clips help to balance the load. For many people I suspect that getting something small enough and light enough to be comfortably carried, plus concealable, is hard to do.
This rig is for my wife, and believe it or not, she has started to carry with it. Woo Hoo!
We were having hard time coming up with a carry option that suited her. Hopefully this is the answer.
