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.
