Well there is somthing for everyone in the gun world.
I have a Pocket Nine and it is the lightest and smallest 9mm on the planet. Mine has been utterly reliable and is a very pleasant shooter. It uses a fully locked breach.
Since it is DAO, you don't want a two pound trigger. I have no problem hitting a man size target at 20 feet just point shooting it. If I aim, using the novak lo mount style sites that come standard on Pocket Nines, it is amazingly accurate.
The measurements, taken from mine, are 1 1/4 inch at the fattest part of the grip, 3 3/4 from the top of the rear sight to the bottom of the grip handle, 5 3/4 from the very back of the beaver tail to the tip of the barrel.
It weighs about 15 ounces empty. It fits in your pocket and gives you some fairly serious punch in a tiny, comfortable package. If you carry it IWB you will forget it is there.
