I thought the pistol was out in January, but they issued this press release yesterday. Either way, it is now available.

UPDATE: Tim, in the comments below, let us know that the pistol is due to be released in may-june 08.

From the press release:

Beretta USA is pleased to announce the introduction of the most advanced Sub-Compact sidearm of its kind – the Px4 Storm Sub-Compact pistol. Built around Beretta’s latest Px4 Storm modular technology, the Px4 Storm Sub-Compact delivers concealed carry handling with large frame firepower.

Available in two calibers, 9mm with 13 round magazine capacity and .40 S&W with 10 round magazine capacity, the Px4 Storm Sub-Compact will be available in all the traditional configurations (F, G, C, D actions) that have made its Px4 Storm full size counterpart a preferred choice of Law Enforcement agencies and civilians across the United States. This new pistol uses a very reliable locked breech, providing a more compact and lighter weight system. Additionally, the Px4 Storm Sub-Compact utilizes a stainless steel barrel which requires less maintenance and is corrosion resistant, making it perfectly suited for concealment close to active perspiring bodies.

“With the launch of our new Sub-Compact model, the Storm family of polymer pistols and carbines is now the ideal suite of firearm platforms available on the market” said Gabriele DePlano, Vice President of Product Development at Beretta USA. “Whether it is used for concealed or open carry, on or off duty, as a patrol rifle or for home protection, the Px4 Storm Sub-Compact family is poised to offer our operators the ultimate in Beretta’s reliability, durability and accuracy in its smallest package yet.”

Hailed by some as the most accurate Sub-Compact pistol on the market, the Px4 Storm Sub-Compact offers absolute reliability and consistent accuracy in a small package. Featuring a Picatinny rail to fit light and laser accessories, the Px4 Storm Sub-Compact also adapts to different hand sizes easily with interchangeable backstraps that are included with each firearm. The magazineÂ’s patented “Snap-Grip” allows for maximum concealability when the firearm is holstered, while providing a comfortable and secure grip when the pistol is being fired. An ambidextrous manual safety, ideally positioned on both sides of the slide for easy access by all shooters, and a low-profile slide catch complete this small yet powerful package. Additionally, a reversible magazine release button, in small or large size, can be mounted on either side for the convenience of the operator. The Px4 Storm Sub-Compact was designed by Beretta USA and will be manufactured in the United States at Beretta USAÂ’s Accokeek, MD facility.
