About the Handgun:
Kahr pistols are striker-fired locked-breech designs, relying on a modification of the Browning dropping-barrel system with a lug above the chamber locking the barrel into the roof of the slide. Although the trigger is designated as double-action only (DAO) by the manufacturer, its operation is actually similar to the Glock, Springfield Armory XD and S&W M&P. True double-action only triggers are designed to completely cock and fire a pistol, allowing for a re-fire operation on a miss-fired round without without racking the slide. Like the other models mentioned, Kahr triggers use a slide-assisted cocking action which removes much of the weight and length of the trigger pull. As a result, the trigger cannot cock the striker on its own, which is functionally much more like a single-action trigger.
About the Manufacturer:
This us company was founded in 1993 by Justin Moon, with the intent to fill a perceived gap in the handgun market for a larger caliber ultra-compact pistol for concealed carry. The company has attained a long standing reputation for quality. In 1999, Kahr Arms bought Auto-Ordnance Corp., and continues to produce their line of semi-automatic weapons, including a long-barreled, semi-automatic version of the famous 'Tommy Gun.'
About the Cartridge:
This cartridge was introduced along with the Luger semi-automatic pistol. The pistol and cartridge was first adopted by the German Navy in 1904 and then by the German Army in 1908. This cartridge has since been adopted by the military of practically every non-Communist power. It has become the most popular and widely-used handgun cartridge in the world. Performance wise, the 9mm cartridge has somewhat more power than the .38 Special but falls well short of the .357 Magnum.
