German Sport Guns GmbH has introduced a combination .410 bore/.45 Long Colt derringer for personal defense. All4Shooters has the story:

The new .22 Long Rifle pistol lines and the 9x19mm caliber semiautomatic version of the legendary Mp40 sub-machinegun design are not the only new products showcased by the GSG – German Sport Guns company at the 2015 edition of the IWA Outdoor Classics expo in Nuremberg − nor they probably were the most interesting after all.

As a matter of fact, the company also showcased the first prototype of its compact, double-barrel, two-shots defense pistol, dubbed the GSG-P.D.R.(“Personal Defense and Rescue“) that should go in production and on sale later this year or early on in 2016, and was conceived as an “all-rounder” defensive piece against home invasions, carjackings, assaults and aggressions in the public way, or as a protective backup for backpackers and outdoorsmen when out in the wild.

Offering a solid, modern and lightweight metal and polymer construction, the German Sport Guns GSG-P.D.R. double-barrel pistol breaks open for reloading and offers two over-and-under barrels which can use .410 gauge shotshells or .45 Long Colt ammunition; the GSG-P.D.R. also features a frame-mounted manual safety on the left side, ad easy thumb reach, as well as a cross-button located on the rear portion of the trigger guard that can be activated when the trigger is pulled halfway to select which of the two barrels will fire first; being the GSG-P.D.R. a double action only design with a long trigger travel, this can be done in total safety.

It’s not clear what the attraction of a firearm like this is versus a more conventional compact or subcompact semiautomatic firearm. As with all firearms like this, price will play a key role in its success or failure.
