I'm only chiming in for the interest in firearms technology, as I have not shot since I was in the infantry - but I still occasionally read about weaponry.
Not buying myself unless I move into a house, and even then I'd likely only get a tactical pump shotgun - but here's a really nifty .380 pistol I saw some years ago - designed for concealment in mind:

Your body has curves, so why aren't pistols shaped to match? The Taurus Curve is the world's first and only curved firearm, engineered to fit the unique contours of your body with no visible printing. An extreme departure from your typical compact .380, you'll find the Curve takes form and function to an entirely unprecedented level. With its patented, snag-free design, the Curve boasts the industry's first-ever
light and laser built right into the frame. It attaches with a built in holster-free belt clip. Exceptionally accurate and extremely lightweight at just 10.2 ounces, the Curve is one ultra-comfortable, ultra-reliable personal defense handgun.
