Beretta® Px4 Storm SubCompact 9mm Semi-automatic Handgun.
Big performance in an ultra-concealable package. You'll be amazed at how many premium features Beretta packed into its Px4 Storm SubCompact. The built-in Picatinny rail and interchangeable backstraps make it customizable, and the tilt-breech system works with the rest of the frame to dissipate recoil to levels far below others in its class. And don't forget, all of that comes in a lightweight, easily concealable package with a width of only 1.42" that won't print. You can look, but you won't find another feature-packed pistol that's this easy to conceal.
