If you are O.K. with a .380 take a look at the Taurus TCP-738. 5.2 inches long. Weight:10 oz. Fits like a glove in my pocket holster, which hides the outline of the Gun. Only 6+1 Rounds though.
If you are 9MM person, I like my SCCY CPX-1 or CPX-2 Just a tad larger. I think it weighs around 15 OZ. 10+1 Capacity.
Also, Taurus is coming out with a new .380 called "Spectrum". Haven't seen one, but I will look at one. They say at the end of March.
The SCCY CPX-1&2 comes with a pinky extension for the Magazine and you can get one from Pearce Grips for the Taurus.
